I have a 09 Mac Mini, 2GHz Core 2 Duo, with 3GB of memory, running Mac OSX 10.5. For the past few months it's been running slower and slower, with PS4 crashing (especially moving layer order) and now in the past week Final Cut 6 has started doing the same. Are there some basic tests I can run to see where the problem lies? As a side note, our wireless network seems decidedly slow(always has really), even though speedtest.net shows above average results for our ISP(see below), skype keeps displaying a low bandwidth warning, just on a voice call. dl: 18.27 Mb/s ul: 2.69 Mb/s ....as another side note. browsing time capsule is much slower than browsing folders on the Mac HD, even though it's connected by ethernet.
