Hi,

Has anybody installed Security Update 2020-001 for Catalina 10.15.7?

Does it break TotalSpaces2?

Am I supposed to re-enable SIP before running the update?

Best Regards,  
J

I’ve installed Security Update 2020-001 for Catalina 10.15.7, and TotalSpaces2 continues to work fine — I didn’t have to do anything.

I installed 10.15.7 now. It does not start up with SIP disabled and so I must change to ‘csrutil enable’ in Terminal of rescue mode. TotalSpaces2 does not work…

* * *

cmd-R  
csrutil disable  
reboot in safe mode  
login but black screen (only cursor is displayed)  
ssh to this mac  
csrutil status : disabled  
but /System/Library is still read-only so I cannot remove TotalSpaces.osax  
reboot then cmd-R  
csrutil enable  
reboot without TotalSpaces2…

I have been putting off updating the 2020-001 Security Update until yesterday. I can verify that TS2 no longer works. It launches but switching to another space redraws the desktop then nothing. A bit of help would be appreciated. Thanks. I should add, I’m running TS2 2.9.8 on an older (Late 2013) iMac.
