Feb 4 ►►Unable to start Diablo 3 Launcher [Solution]◄◄ I have been seeing reports that players are having issues running Diablo III by clicking the game client's icon in the Diablo III folder, and after having experienced the same by testing on my installation, I have determined the cause and found a series of steps that will resolve this issue for you and allow you to once again use the Diablo III icon to launch your game as you did prior to this patch: 1) Navigate to the folder containing the Diablo 3 game executable and the Diablo 3 Launcher. 2) Delete the file Diablo III Launcher (move to trash via CMD-Delete/Backspace). 3) Run the Blizzard Desktop App. You should already have this as it is required to run Diablo 3 as of 2.0.1. If your BDA is set to automatically apply updates it will download a new fully functional Launcher app and place it where it belongs in your Diablo III directory. If your BDA is set to the Never automatically apply updates option, then you will need to manually click Update and the BDA will then perform the update operation. The issue should now be resolved regarding the Diablo 3 app failing to run the Launcher. It seems that the initial patching download from the CDN servers had a corrupt file (the launcher) which appears fixed as of today and deleting and redownloading it resolves this. Good luck, and enjoy the great loot hunt! :) ________________________________________________ Technical Support MVP Prime Directives: 1. Serve the public trust. 2. Protect the innocent. 3.

Mar 8, 2016 Low FPS in Windowed (Fullscreen) Mode We're aware of an OS bug where running some games in Fullscreen (Windowed) mode an cause a severe drop in FPS in-game. We anticipate this is addressed in the next OSX build. In the meantime, there are two different workarounds that may help! 1. Running the game in Fullscreen Running the game in fullscreen should not have the FPS degradation above. This does limit some functionality, such as ease of tabbing out of game without redrawing your desktop and Applications. 2. Minimize all background windows using Flash (including the Blizzard App) Flash applications drawn behind a Windowed (Fullscreen) application cause FPS loss. The Blizzard Desktop App uses Flash elements as well, so minimizing this on launch can help. 1. Open the Blizzard App > Settings. 2. On the General Tab, locate the When I launch a Game dropdown. 3. Select Close the Blizzard Window 4. Click Done to finalize your changes.Glaxigrav0 Mar 8, 2016

Mar 5 Black Screen on Start Up Game was running fine until a few minutes ago. Left to make dinner, came back and tried to start it up again and nothing. I just get a black screen with the spinning rainbow wheel and nothing is responsive. I've tried reinstalling everything, resetting the game options, clearing the caches, and everything else on the troubleshooting page here: At this point I really don't know what to do with it. The only other info I can give is if I try to launch the game while it it reinstalling before it hits the optimal zone, it launches zoomed in to the top left corner and then I get the same issue. Any help would be appreciated.Momonomo31 Mar 5
Mar 4 Diablo 3 Battle.Net launcher stuck on Update I followed the directions here (applying global permissions to enclosed files for the D3 game, and Blizzard folders) and that does not work. When I open or click on the Diablo 3 launcher I'm prompted for my password which I enter, the Launcher looks like it quits and reloads itself, there's an 'Update' button instead of a 'Play' button. When I click Update, I get a message: "Please try again after logging on as an administrator" With a help link going here: That eventually leads to this forum.. I have also tried uninstalling and re-installing the game and that worked once but after I quit the game and came back it's back to the same broken Update button.fredelement45 Mar 4
Feb 25 Season 16 not working I have Patch 2.64 installed but I am not seeing the benefits i.e. ring of Grandeur or any others. Do I have to do anything special to make it happen? I had the Season 15 benefits. I mostly play solo. Thanks...ZinjianZool3 Feb 25
Feb 22 MacBook Air 2018 - Optimal Settings Hi all, I'm new to Diablo and have one of the new Macbook Air's, released late 2018. I've searched the forums for some guide on optimal settings but I haven't found a relevant thread. I was hoping that someone might have some advice on the optimal settings to get the best performance out of one of the new MacBook Airs. Device detail: MacBook Air (Retina, 13-inch, 2018) Processor: 1.6 GHz Intel Core i5 RAM: 16 GB 2133 MHz LPDDR3 Graphics: Intel UHD Graphics 617 1536 MB At the moment, I have played about 15m using the default settings (which is largest resolution, everything set to high). It plays quite well, but I haven't seen a lot of action and it is a little jumpy in general when moving around. I don't have a lot of time available for gaming and I suspect going low on everything and then choosing a smaller resolution will improve this greatly and I will tweak settings until I find something that works. But I thought maybe someone else has spent a bit of time doing this and could potentially save me some tinker time and help me maximise my time smiting evil. Thanks in advance.Mnky2 Feb 22
Feb 22 Diablo 3 on 64 bit yet ? Saw an old thread from 2017 about this. Diablo 3 on 64 bit yet ? Running Metal/Apple ?? Did Windows D3 users base finally go 64 bit as that was the hold-up in old thread ? !!KillerB2 Feb 22

Feb 11 D3 Working on my MBP ... finally?!? I have to admit that I agree with all the people complaining about this issue... Blizzard screwed us on this last update for Season 16 and forces your hand to get it working. Admittedly, Apple has done the same thing because my iTunes stopped working properly in Yosemite and I was told to upgrade to get it to work?!? Seriously... Anyway... here is my solution! It may or may not work for you but this was the only way for me to get it to work WITHOUT buying anything new! FIRST - What is your computer? Can it be upgraded to mac o/s 11.11.6? ... mine could, I just went to 11.11 when it first came out and it blew chunks so went back to a stable build, Yosemite! IF YOU CANNOT UPGRADE TO 11.11.6 THEN THERE IS NO SOLUTION FOR YOU ASIDE FROM UPDATING YOUR COMPUTER... sorry. Now here is where I wanted to NOT lose my Yosemite because I have everything working flawlessly in it... well not iTunes or D3 but I could live without them. I have a mid-2009 MBP and added a 256G SSD drive last year... LOVE IT! Definitely worth the money. Here's how I play D3 now! 1. Clear hdd space, enough to make a partition 40-50G. I still have like 60-80Gigs free after the new partition was created so I kept free disk space. 2. Reboot and select recovery on boot up (hold option at start up). 3. Recover Yosemite to the new partition. 4. Upgrade to El Capitan on new partition. 5. Installed D3 and VIOLA!!! Everything worked great! This stinks because it takes up hdd space but if you want to play on your mac... then this is what you have to do! cheers!Jagered724 Feb 11
Feb 6 Running D3 in 10.10.5 Yosemite worked til now Edit: I see that, to my surprise, as of a year ago the minimum system requirements are OSX 10.11, despite my being able to run on 10.10.5 until now. I do not plan on updating my OS, so I am wondering if this patch has finally broken the game for 10.10.5 and if anyone else is in my position and has found a workaround for running it in Yosemite. I understand it is not officially supported. Thank you. BorisBoris4 Feb 6

Feb 4 Black screen when starting up game following patch Hey, Blizzard. I've been playing Diablo 3 for the last three weeks with no issue on my Macbook Air (OS X Yosemite). I updated the game this evening, and now I only get a black screen with a scrolling rainbow wheel when I try to open the game from the interface. I tried restarting and the scan and repair feature, but to no avail. I am using my laptop keyboard and a Logitech mouse. Any help is appreciated; thanks!MortySmith8 Feb 4
Feb 4 Where is the D3Prefs.txt File on macs? *HELP* There is a workaround that has worked for me concerning unsupported video cards on the Mac that I worked out from the info for the PC workaround ( Hey Guys, I'm trying to work around a non supported graphics card. I found the work around below but where is the D3Prefs.txt file on a mac? When I look in the folder below its empty? On the Mac: 1. You're going to have to show hidden files/folders, I used Onyx. 2. Go to your home directory (i.e. your name), then find the grayed out folder Library (it's normally hidden). 3. Traverse to Application Support > Blizzard > Diablo III 4. Open D3Prefs.txt with your text editor and follow the same steps as the PC stuff: Change: - DisableTrilinearFiltering "1" (from 0 to 1) - HardwareClass "1" (from 0 to 1) Save the file and close it. 5. The one last thing I had to do was play it in windowed mode: Added Change (in D3Prefs.txt): - DisplayModeWindowMode "1" (from 0 to 1) Save the file and close it. This should prevent the black screen and initialize the first cut scene, you can proceed to watch it, or escape out of it and then you'll be presented with the login screen for D3. As long as you play in windowed mode, you should be able to play if you were running into the black screen.bigPToronto60 Feb 4
Feb 2 BLZNTAGT0000032A - not updating I haven't played in yonks, so I'm updating, but it's not working. I'm on a Macbook Pro, OS X 10.11.6. I click on, it says it's updating and gets to 70% or so (that's an eyeballed estimate based on the progress bar), then it freezes and gives me BLZ . . .32A error, saying it'll keep trying in the background. It's been two days now, though, so I don't think it's happening. I went through the steps in and I have no idea what I'm doing on step 4. I read through as well--I tried the first solution; no luck. The next solution I tried was "Resetting permissions." I can't reset the permissions on the Blizzard folder in the /users/shared folder--"read and write" is greyed out on "everyone." Not really sure where to go from here... suggestions?Marmosette8 Feb 2
Jan 28 BLZBNTAGT000008A4 Hello, I tried to install Diablo 3 again on my macbook. It downloaded everything fine. But, the last 124mb will not be downloaded. I always get the message: Failed to download files from Blizzard. BLZBNTAGT000008A4 I tried all the suggested solutions and none of them work. My mac is updated to the latest versions as well. I would be more than happy to hear any news on this. Best regardsGivious2 Jan 28
Jan 22 Pixelated Graphics after upgrading to 10.12.4 Ever since upgrading to macOS 10.12.4, I've noticed that some of the graphical effects in the game become pixelated. Some examples are the lights attached to buildings in New Tristram, and also Zoltun Kulle in any town (when he's standing by Kanai's Cube). I don't remember seeing this effect after installing 2.5.0, but only after upgrading my OS. My computer is a 2015 27" iMac with an AMD Radeon R9 M395 w/ 2GB RAM.Adeese50 Jan 22

Jan 5 Unplayable on MacOS Mojave Installed Mojave today and the game is not playable. Graphics are choppy with lots of mini-freezes. Can't play hardcore like that :-( It appears the problem lies more with Apple than Blizzard as they must approve new drivers from the video card manufacturer. In either case, I'm not hopeful that this will be fixed and it looks like the end of the line for me with Diablo. I'll check back in the the meantime, GL fellow adventurers!

Dec 24 New iMac 5K keep crashing... Hi: Just replaced my old iMac 27" (late 2012) with a new 5K one (mid-2017) and I find that I can not get Diablo III to load successfully. Played fine on my old one, the fan would just run like mad but it never crashed. I managed to play 10min on the new one, using one of my older characters, but the new Necromancer is not loading. It starts, allows me to choose my character and then crashes and returns me to the desktop. I have tried this at the default resolution (2560x1440), and the higher (3200x1800). Since the computer is new and just came yesterday I bought it with the default 8GB memory (knowing I would be upping this soon) where my older iMac has 24GB. Could this be it? Will I have more success once I update the memory to 24GB or higher? Thanks in advance for the help. I don't play as often as I did years ago, but not being able to play at all now is bugging the hell out of me.Impaler8 Dec 24

Dec 17 Mouse cursor frozen (iMac) After the recent update (~1hr ago), the mouse cursor is frozen. The mouse moves until the connecting screen. After that it is frozen. Keyboard works. On screens where the cursor is above something, the item beneath does light up and I can click it. If I place the cursor over the 'resume game' button and click, the game attempts to load but is frozen. I was playing before the update with no problem.Kaleva19 Dec 17

If I hold down the left mouse button it seems to be okay, but as soon as I let it go it stutters all over again. I tried buying a new mouse, replacing my moousepad, reinstalling diablo 3, and reinstalling Razor synapse. Using other mice. It doesnt matter what moouse I use it is the same thing,,,, HELPGreezon26 Dec 17

Dec 17 Mouse/Cursor Issues on MacBook Pro I have a MacBook Pro and I've read previous post about slow or lagging mouses but my cursor is completely frozen.

Dec 17 Game won't start on MacOS Mojave(10.14) Hey, returning player but I got a new computer, MacOS Mojave running (10.14) just downloaded blizzard app and installed Diablo III +RoS and I've been trying to fix it all day. Any suggestions? I've restarted the computer several times, even disabled firewall but nothing works. I am really clueless, tried launching it via, diablo III launcher and just clicking the game itself in its folder. Full accessability permissions on aswell for all three of those. I can't launch the game, there is no error message at all, the game appears in my dock but when I right click it it says 'Application not responding' so I have to force quit it because it never launches due to this.Torurusu4 Dec 17
Dec 17 Mouse hangs to screen edge on Mojave Beta Diablo has become almost unplayable on Mac: mouse hangs and freezes for a few seconds whenever it reaches the edge of the screen. I can still move it, but it resets its position many times per second. Buttons freeze as well, both mouse and keyboard. I'm under Mojave Beta so I know this could be the culprit by itself, but it's better to point out the problem. I'm running the game on a MacBook Pro 2017 15", currently at 1680x1050 resolution (which is bad, but looks like performance issues are pretty common these days on Mac). This happens regardless of the mouse I'm using. Tested with a Logitech G502 Proteus Spectrum and a Corsair M65 Pro RGB.Asterion2 Dec 17

Dec 6 iMac Cursor Disappears Did not see a cause/fix in forums so here's the issue: Wife plays a WD & sometime during play she will lose her cursor - completely! It's invisible! I can take over to get her out & exit the game "by feel" but there's no cure as I can tell. This has happened on two differrent iMacs running different OS, hardware, etc. Restarting the game is the only fix, do you have any idea of the cause? Thanks.GwydionM8 Dec 6
Dec 3 Gameplay won't start iMac Pro I have an iMac Pro and installed D3 on it. The opening video plays, it goes through connecting online successfully. Brings me to the character screen where I can select a character to play. Created a new S14 character. Went to start the game from the character screen, screen fades to black, and I am returned to the Finder. client is still running. Not sure it won't start gameplay, but every other part of the game loads okay up to that point. And this is a brand new install on macOS 10.13.6.ThatGuy25 Dec 3
Dec 1 Mouse cursor lags on Fullscreen Mode I'm still having issues with the mouse cursor lagging on Fullscreen mode. It appears to work fine on 720P full screen mode but at native resolution the mouse is basically stuck and the game becomes unplayable. It's been a long time since the problem has been around, I was hoping Blizzard would have fixed it by now. The issue is present in High Sierra as well as the latest MacOS Mojave which is close to Gold Master and I don't think the fix will be provided by Apple's side. I hope Blizzard does something to address these issues.yamcha672 Dec 1
Nov 30 Cheese grater Mac Pro GPU for Mojave Here's a list of cards that work with ROS: I learned too late that the RX580 Sapphire Nitro + Super OC Edition is not on the list.

Nov 16 iMac and gaming question AMD 570,575 or 580 Hey all, I thought you would be a good crowd to ask this question. Which graphics card is sufficient for Diablo? I don't plan on doing much else for gaming on the iMac, maybe the odd game of Starcraft or civilization, but I want to be able to play D3 and have the iMac future proofed enough to stand a chance with D4 whenever that gets released. Curious if you think the 570 is sufficient for my uses? THanks!Pman5 Nov 16
Nov 16 Display errors Hi there, I hope you will understand my english :-) I play D3 with my iMac 5K 27 inch with a Radeon 580 GPU. I use 2560x1440 resolution. For example, all "hanging lamps" are graphically defective, they look strangely "pixelated". I use a clean fresh installed Mac OS 10.14.1 and a clean and fresh D3 installation. Any suggestions on this? :-)MrDustyBits9 Nov 16
Nov 14 Slow mouse cursor Hi My mouse´s cursor it´s moving very slow in game since yesterday. The strange part is that I had played earlier with no problem.

I spoke with the blizzard support but they was not able to help me. Thanks!RMEP4 Nov 14
Nov 11 High Sierra 10.13 - Low FPS Since upgrading to the 10.13 GM Candidate Diablo 3 is running extremely poorly in regards to FPS. I used to run it capped at 60fps, now it struggles at the same graphics settings to get 15fps! I'm running on a Late 2016 MBP with the Radeon 460. Anyone else notice poor FPS with High Sierra?Brandonee36 Nov 11
