[Lex Computer & Tech Group/LCTG] Would you recommend an upgrade to MacOS Tahoe?

[Seth Silverman]

I am running the latest MacOS on an M1 MacBook.  The risk of not 
upgrading the OS to the latest is that Apple stops shipping security 
updates for older versions.  I think they usually keep updating the 
previous version for a while and every once in a while, you may get a 
security update on an earlier version, but just like with iOS, sometimes 
there are vulnerabilities that are only fixed if you are on the latest 
OS.  I think that is a very important factor to consider.

As for compatibility with older apps, it is a concern.  I have a really 
old MS Office installed that I keep just in case, but rarely use it.  It 
does work fine when I do use it.  I can't speak about other applications 
like Photoshop and MATLAB, but there is a good chance it will still 
work.... but don't hold me to that :-)
