When Lightroom is opened (sometimes as focused app, sometimes in the background), if freezes my entire Mac (even the mouse stops working). It happens at least once a day. I have yet to identify a specific workflow when that happens. The only way out is a cold reboot.Here is my system info:Lightroom Classic version: 7.1 1148620 License: Creative CloudLanguage setting: en-CAOperating system. Operating System:MacOS X 6.13.2 High Sierra Exact Lightroom Version (Help menu System Info): 6.3 An Adobe forum indicated that the problem is fixed with.
I had a quick look and yes Photoshop CS3 does work in High Sierra, but Lightroom 4 has No Data which is bit telling.
The App is not the be all and end all, but it is a good guide.
You could try re-installing Lightroom 4.
I have just installed an old copy of Lightroom 4 on my macOS High Sierra partition and it works fine.
Interesting.
