I'm an old Windows/CCleaner user but have 100% left M$ a couple(?) years ago for Apple with a MacBook Pro 15", touch bar, 4 USB-c ports, and yes--a SSD. (Also an iPhone 7 plus and an Apple Watch too.) As some of you might imagine I have spent many hours with Apple Care. I have one outstanding months long unsolved problem to share elsewhere here maybe. I suspect talking to Apple Care that CCleaner might be a great 3rd party tool that Apple needs however they repeatedly don't recommend CCleaner. And only recently have I gotten some okays to run Malwarebytes--neither of which are found in the App Store. Apple's concern may be that running CCleaner will (and does) mess up some things? IMO, Piriform's goal should be to get CCleaner in Apple's App Store de-tuning it down to where it causes no problems. ...I'm waiting. App Sandboxing--fascinating read... So what is left of CCleaner if it goes along with App Sandboxing and could then be listed in the App Store? I wonder if this is the same reason why Malwarebytes isn't listed in the App Store?

What trouble could I possibly get in? I used and liked CCleaner for years on my Windows 7 PC but over a year or so ago abandoned the PC for the MacBook Pro. (Gaming now relegated to consoles only.) So so far I haven't found any real need to use CCleaner on the Mac nor has Apple once suggested that there is any need. Yet CCleaner has a Mac version and claims some need. I'm reluctant to dive right in but just continue to keep an eye out. Would be very interested to hear here from any Mac users who find CCleaner of value/useful to them? Other then Malwarebytes there has been no other 3rd party care I'm aware of needing. Since storage is an ssd there is no defragging but my backup drives are hdd. Apple to the common user finds no need to discuss any of this which coming from the PC world I find refreshing and hope it lasts.

So you would rather install an image then defrag the Registry? Interesting. I went 1.5 years on my Vista installation. But I used CCleaner then I periodically, whether it needed it or not, also defragged the Registry. Baring the disaster that would necessitate it I don't see running an image every 6 months myself. I would still wish Piriform consider a complete Registry maintenance built into CCleaner.

This confirms what I suspected. I'm sure it has been asked a million times but do you know why, if CCleaner does so much for a healthy computer it doesn't become the umpteenth freeware to also do Registry defrag, compress, & optimization? Rather then use umpteen different utilities--I would rather use one. I'd be interested to know? Thanks for your response.

I added and removed games for over 1.5 years and during that time I ran a 3rd party program that defragged the Registry removing deleted blank areas and shrunk the file sizes down. This was suppose to help things boot and run faster--whenever the Registry had to be accessed. The question now is whether this is still necessary to do at all with Windows 7? And the further, of course, question here is whether CCleaner does this as part of its Registry cleanup? Does it remove empty space where lines of code use to exist, then defrag the files so they are compact like new? If CCleaner doesn't offer this as an automatic part of cleaning up the Resistry wouldn't it be a nice idea if it did? Pros & Cons? If it doesn't does anyone recommend and use another 3rd party program for Windows 7 that does? Thanks.
