Help with Ccleaner

knightstyle

Several people have recommended Ccleaner so I tried it, liked it an decided to buy CCleaner Professional (for Mac)
But after downloading it I cannot open it!  I get this  https://hosting.photobucket.com/images/zz293/stuff4sale4/Screenshot_2020_06_09_at_12.24.36.png?width=140&height=95&fit=bounds&crop=fill
I have asked for help but it looks like a long wait so am asking on here if anyone can help me?

Try downloading with another browser,ie Firefox.

CCleaner receives less enthusiasm, now that we're past Windows XP. 

Quite why anyone would want to use it on a Mac, I cannot imagine!

Thanks, replaced it with new download on Firefox but get the same result.

If your sure it is malware free
Open System Preferences > Security & Privacy:
Click Open Anyway

I had the same problem.  Once I had completed the latest OS update I found that CCleaner is no longer compatible with iOS.  In order to maintain my mac I have removed both Malwarebytes and CCleaner and replaced them with CleanMyMac.  Wish I had done so years ago as the difference is huge.  Cleaner and faster mac running quieter and quicker.  First scan took nearly 2 hours but subsequent scans take less than 15 minutes.  Highly recommended.

you shouldn't need third party software to clean the os.  can't you clean the os in settings?  i uninstalled ccleaner > 5 years ago

Two hours?? Is that with an SSD?
Fifteen minutes is too much.

Well I ended up with a refund.  Those who say i should'nt need Ccleaner what do you use to remove unused items and reduce clutter EASILY on my Macbook?   Clean my Mac didn't get good reviews so anything better?

What makes you think that you need to "remove unused items" and to "reduce clutter" on your Macbook?  Have you not got gigabytes of unused disk space?
