Windows PC environment

Win10 256 GB SSD

Install macOS 10.13 High Sierra

Speed after installation: very smooth Problems: (1)font is blur: although it's still acceptable, but the font is a little bit blur. Please use this VMware command line to change the resolutions. You can change the '1980' or '1080' to whatever your display fits. /Library/Application\ Support/VMware\ Tools/vmware-resolutionSet 1920 1080 (2)disk space is not enough for some large App: I strongly recommend to set your VMware disk to above 60 GB, or you may can't install some large App like Android Studio or X code.

Install macOS 10.15 Catalina

Speed after installation: not very smooth Problems: (1)too slow to install VMware tools (darwin.iso): It took very long (around 15mins) to install VMware tools. I've thought the system is frozen and I restarted VMware for two times, but actually it didn't. (2)too slow to open an App: too slow to open an App such as Finder or Note. Finnaly, I gave up macOS 10.15 Catalina and reinstalled macOS 10.13 High Sierra.
