My perfectly fine iMac currently runs on El Capitan - but I'm wondering if (and how) I might upgrade. I'm currently experiencing sound/video lags on QuickTime movies which I can't seem to resolve, and iMovies isn't an option as I can't update that either (currently version 10.1.4). I am a professional musician, so the sound/visual sync is pretty critical. Thanks for any advice!
Got a tip for us?

My 2011 iMac is running high Sierra and it’s working great. Here’s how to upgrade:

How to download and install macOS - Apple Support
Download and install current or previous versions of the Mac operating system on compatible Mac computers.
Thanks! I will give that a go - hopefully that will resolve my sync issues (or at least give me other options).
How much RAM do you have? Also depends on what type of boot drive you have (HD, Fusion or Flash). If HD or Fusion then replace with an SSD. If Flash then it may be full enough to cause issues with the software caches. About 30% free is the rule of thumb but it depends on the size of your Fusion drive obviously.
