Yeah, defragging was useful about for the disks of about 15-20 years ago. By 10.7/10.8 I had dropped the use of just about all third-party maintenance programs. Defragging isn't the panacea that people think it is, and is not needed on a Mac except in very unusual circumstances.īy the time Snow Leopard came about, many of the maintenance routines that 'power users' had become accustomed to running had become integrated into OS X and automated. I remember when I maintained industrial computer printers which were accessed via dedicated Windows-based computers, that we had a 'Defrag' program which worked wonders.ĭoubtful. What problems are you having that you think you need to clean it? Is there anything reliable to clean up an iMac running 10.6.8 Snow Leopard? One is malware, which makes itself known by popups and the other is 'cleaner' utility and a not very good one and totally unnecessary. There are actually two things called MacKeeper. SO - went to OnyxMac and saw a 'Free Download' of 'MacSpeed Scan' soi i tried that & the download was 'MacKeeper' - I immediately put it in Trash but this gives me NO confidence in Onyx! Several replies suggested using 'Onyx' to clean up a Mac & (maybe ?) speed it up a bit. You're wise to be suspicious and even wiser to check before trying it. It's malware, as is anything that is pushed via popups.

I keep getting popups advertising MacKeeper - which makes me suspicious, so I searched 'MacKeeper' on this forum and it sounds like a bad idea.
