iMovie on a 2010 iMac was starting and running slow: 2 simple steps solved that

Posted by jpluimers on 2017/02/27

iMovie on a 2010 iMac was starting and running slow. During startup, it wasn’t using much memory, but during editing it did: less than 2 gigabyte out of 8 gigabyte free memory left.

The hard-disk was like 30% full, there wasn’t much in the cache, few processes were auto-starting and the recycle bin was almost empty.

So my first thought was adding more RAM (which is easy): duplicating it to 16 megabyte was easy and not expensive when you look at the Amazon prices for it.

After that it was faster, but not really fast: especially the loading was still slow (less slow than before, but still taking minutes).

Then I scanned for permission issues and there were quite a few as the machine had been getting updates since 2010. So I repaired the permissions using disk utility.

Now iMovie loaded much faster as well: in under a minute.

So out of 17 Ways to Speed Up Mac OS X Lion –, only 2 steps were really needed so far.
