MBP M1 Max with Monterey - so the latest kit and OS - works fine except that alot of the extensions are not compatible. Looks like you cant win - as soon as you upgrade the hardware then the software / extensions is a problem in the short term until extension creators update
Thanks WeAreJohan. I am concerned that my Mac’s model (late 2015) will be the factor that brings me undone. Any thoughts on the model’s factor. I had previously had sketch up 2016 and everything went pear shaped with an upgrade and it became totally unusable.
My iMac is a late fully stocked 2015 model as well, but haven’t used it in months (waiting for the 27" update), before that it worked well, hope that helps.
