My MacBook Pro Intel keeps crashing / restarting without me doing anything. I get an error report stating a "WindowServer" problem. This has happened only after updating to Mac OS Tahoe 26.2.
Can /should I try to reinstall Mac OS Sequoia?
MacBookPro16,2, BootROM 2094.40.1.0.0 (iBridge:
23.16.12048.0.0,0), 4 processors, Quad-Core Intel Core i7, 2,3 GHz, 32 GB, SMC
Graphics: Intel Iris Plus Graphics, Intel Iris Plus
MacBook Pro 13″, macOS 26.2
May be related to a third party process that is running on your computer and causing a conflict with the OS. The WindowServer is a catch all for many processes that crash and will cause a restart. If you have installed any AntiVirus, VPN, Cleaners (CleanMyMac or similar), then you should remove them and test again. After that I would recommend posting the free EtreCheck report using the Additional Text option when posting, and that will give much more details about the crashes on your computer along with the processes launching on startup.

Downgrading to Sequoia is possible, but not easy. A clean install of either OS would wipe the drive and remove the third party processes that may be causing the problem. The choice is yours on whether you want to Factory Reset to start fresh and install applications again one at a time or try removing the processes identified in the EtreCheck report. I would not recommend a complete restore from backup if you choose the Factory Reset, because that would just load the problem files back and you would be in the same situation.

Mac Jim ID has posted a really good summary of steps you should consider to move forward.
If you have questions, please ask for refinement on ANY issues.
That's why we informally call this "Apple discussions".
thanks! I will check that
