1.23.00 patch problem with iMac

Mac Technical Support
Hardware: Late 2013 iMac
Processor: 2.7 GHz Intel Core i5
Memory: 8 GB 1600 MHz DDR3
Video: Intel Iris Pro 1536 MB
OS: 10.13.6 (17G7024)
ASUS VE247 second monitor plugged into Thunderbolt port via HDMI adapter
Monitor resolution: 1920 x 1080 in both monitors
StarCraft version: 1.23.00.6342

Problem: Large map shows up normally and then goes black in all scenarios, even for areas that should be visible. The small map shows up normally. The cheat code "Black Sheep Wall" has no effect in changing this. Changing the game to standard definition (F5) shows all visible game units. This problem occurs in both 32- and 64-bit versions. Game is being played on the built-in monitor, although the bug is also present when being played on the external monitor.
Game: StarCraft:Remastered

I helped Mendax compose the above Post. I helped him set up the game for x64 rendition.

Prior to today's Patch, all was well with Mendax's computer. No prior problems playing SC:R.

In contrast, my Hackintosh has no problems with the new x64 game parameters.

[System Specs:]

Corsair HX750i Platinum 750 Watt PSU
UNITEK 10-Port USB 3.0 Hub

The only difference I can see at this moment is that I use the Discrete GPU - MacVidCards' GTX-1070 8GB Card, and Mendax uses the Integrated Iris Pro Graphics' Card. Could the problem be the Iris Pro???

Maintenance Patch 1.23.0.6347 has not fixed this issue.

Turning off real time lighting in the Options is a workaround for this issue. There is a bug that turns on Real Time Lighting by default. It should be OFF and DISABLED for Intel Iris-based GPU's.

This is due to the 2GB VRAM barrier. Integrated Cards, (EVEN WITH 2GB RAM), STILL will NOT be able to use Real Time Lighting, BECAUSE they share System RAM.

Grant Posted in the General Forum in the "Patch 1.23.0 Notes" Thread about turning OFF Real Time Lighting on Systems with the Iris/Iris Pro Graphics.

This bug, apparently, will be addressed and the Lockout that was formerly in place preventing activation of Real Time Lighting on Integrated Cards and Discrete Cards with LESS than 2GB VRAM will be restored.

Until then, as Mendax has Posted here, turning OFF Real Time Lighting is the workaround for Apple Systems with Iris/Iris Pro Graphics.

That did the trick for me. Thank you!

Everyone,

Mickaël, (a Developer), Posted in the "Patch 1.23.0 Notes" Thread in the General Forum.

A new Patch has just been released that once again TURNS OFF/DISABLES Real Time Lighting permanently on Macs with Iris/Iris Pro Graphics. Highly recommended to Update.
