There is no reason to ever install or run any 3rd party "cleaning", "optimizing", "speed-up", anti-virus, VPN or security apps on your Mac.  This documents describe what you need to know and do in order to protect your Mac: Effective defenses against malware and other threats - Apple Community and Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support.  


There are no known viruses, i.e. self propagating, for Macs.  There are, however, adware and malware which require the user to install although unwittingly most of the time thru sneaky links, etc.   


Anti Virus developers try to group all types as viruses into their ad campaigns of fear.  They do a poor job of the detecting and isolating the adware and malware.  Since there are no viruses these apps use up a lot of system resources searching for what is non-existent and adversely affect system and app performance.


There is one app, Malwarebytes, which was developed by a long time contributor to these forums and a highly respected member of the computer security community, that is designed solely to seek out adware and known malware and remove it.  The free version is more than adequate for most users.

If you have a question about a particular VPN service, it may be best for you to provide a new post along with the name of the service to help you better understand that issues that may arise. That topic would be better suited in a new thread as opposed to one about Mac Cleaners.


In the meantime, you should use the Search option on the top of the page to find specific information about the service and the use case in general. As for your scenarios provided, on a public Wifi I would never make financial transactions that would require privacy from a VPN or trust the VPN service with the financial data that I am sending to them. If the service is a free VPN, you must ask yourself how they are making money. I can guarantee you that they are monetizing the information that is sent to them. The latter is simply illegal for violation of sites intended use. I'm not implying that you would be charged in such a case, but if this is what the VPN service is promoting to you, that should tell you how "reputable" they are.

Having trouble with TimeMachine - can't run backups. Deleted LocalSnapshots and still cannot backup. Moved Downloads to an external SSD (~20GB) and Emptied the Trash (~19GB)....

Ran EtreCheck, which tells me I'm dangerously low on space on my 500GB SSD, but 45% of it is "Unknown" in the pie chart. Ran "Storage" and "Clean up" after granting Full Disk Access, but EtreCheck reported it could not free up any storage space.


Attached my EtreCheck Report... Any suggestions?

I suggest removing BitDefender with the uninstaller for the app and doing a new post otherwise it may get lost under this thread. I would also include the new EtreCheck report after BitDefender is removed.

VPNs are good to a point.


Their upside, you get access to international sites that otherwise may not let you have access.

You do have to still be careful of copyright rules in your own country.


You also have to keep in mind when a VPN is active your WiFi networkable printers may no longer work over WiFi, or any WiFi sharing within your place because those depend on the IP your Mac is transmitting, which differs when it is on VPN. Printers are easily enough to resolve because you can print to PDF and print the PDF later when off VPN.


Many offices and schools limit your access to their network by giving you a VPN to connect to. Keep in mind while you are on their network, they may want you to install keyloggers so they can monitor your work with them.


The downside of VPNs, is they open you to a gateway where the VPN owner can treat your machine as a file share and inject in your machine malicious files unless you setup your sharing preferences right, and their access to the internet may be slowed by the VPN host.


We can carry on the discussion on VPNs on a separate thread since that's really a different topic.

If you are on a public WiFi, you need to learn to share the bandwidth with anyone else on the public wifi.

If you are going to hog the traffic with an ultraslow VPN, you are going to hog their bandwidth.

You know, I go on a public WiFi on a bus every morning to work. That's my only change to play Simcity, and it barely is able to manage the traffic of that. Probably because someone else is trying to VPN stuff over it at the time. Be mindful that others need the bandwidth just as much as you.


VPNs are shared resources anyway, and take a lot of traffic on any resource.

System Preferences is the utility under the Apple menu to access System Settings on Mac OS Monterey (12.x.x) and earlier. System Settings replaces preferences on Ventura (13.x.x) and later. We are now at Sonoma (14.x.x). This is where it is essential that you start your own topic thread (clck on Ask the Community above) so you can get focused solutions that are relevant for your configuration.

"Can you help? My Mac is restarting quite often and I am getting the busy ball ALOT!"


Please start a new topic thread regarding this issue. You may need to run Apple hardware diagnostic if possible.

If not, bring it to an authorized service provider if you have a chance to backup your data after holding the shift key on startup to run in safe mode. If you still restart automatically a lot, there is likely a hardware issue with the computer that can only be solved by an authorized service provider on http://www.apple.com/buy

Public wifi sites do not have the bandwidth to do streaming video. You end up hogging the bandwidth of anyone else on that public wifi. Don't do that. It is selfish and rude to do so.
