Hi Gang
I did quite a bit of editing on older Mac Desktops (and) PC's 20 years ago. Not everyone will agree here, but I found (as long as the applications were all up to date), the main editing machine, (offline), never became vulnerable to slow down's, glitches and just over all lag of performance. It 'appeared' much of the slower performance may have been due to the endless Operating System updates and security updates. When possible, I developed a method of downloading the updates or patches to another online machine, then installing them to the main editing machine. Some will say this can no longer be accomplished (not practible), because most of the system updates REQUIRE the system be online at the time. And I'm sure there's other reasons as well. Any other opinions regarding this? You can see my specs in my profile.
Thank you for your opinions ...
