I know but from what I've read here it's pretty common for it to happen
That's why you download the iso with a download manager but some people will never learn.
You know that I've just learnt something...
Never in a million years would it have occurred to me to look for update files anywhere other than through the iTunes/App store apps/software. I did some googling, and came across the the files, in the Support Section... which would presumably allow you to download using a Download Manager...
Quick question though - searching for Mountain Lion, provides the various update packs - and not the actual "first" release, which would presumably be the complete package, as it were, that the sequential updates slotted on to... So to download the primary file - one would still need to go through the App store, which would not be possible via a Download Manager?
Is that last bit correct - or am I missing a trick?
