System Boot up takes twice as long

Hello All, I have a 2017, 4K, 21.5 inch iMac running Big Sur 11.6.1 via 16 GB ram, i7 chip and 1 TB Fusion drive. Startup from sign-in was 30 secs now 70 secs just started over the past few weeks. No new downloads except Apple updates. Can you please suggest some practical steps. Mike99

Delete Sophos: How to Delete Anti-Virus, Cleaners, VPNs,… - Apple Community. Mac computers do not need any sort of anti-virus, cleaners, VPNs, etc. The only thing they are good at is creating false marketing promises and taking consumers' money. They are all scams. In fact, anti-virus and other cleaners cause performance issues, security issues, and make macOS appear buggy. Your Mac is far worse with these types of Apps installed. Mac computers have protection built-in, which is the best protection for your Mac. For specifics on macOS Security, see: macOS - Security - Apple and Protecting against malware in macOS - Apple Support. Mac computers also have built-in storage recommendations: Optimize storage space on your Mac - Apple Support. You can even use the built-in macOS Firewall: Block connections to your Mac with a firewall - Apple Support. Other than that, all you should do is restart your Mac approximately once a week and keep macOS up to date: Update macOS on Mac - Apple Support.


Also, your Time Machine backup is out-of-date. Make sure you have a backup!

Welcome to Apple Support Communities.


I believe we need to proceed with an EtreCheck report. EtreCheck is a useful App to diagnose and identify issues, both hardware and software. It is trusted by many users. Please follow the steps outlined below:


  1. Navigate to: https://etrecheck.com and get the free version of EtreCheckPro.
  2. Download it. It is a free and trusted app. It is often recommended here on Apple Support Communities. 
  3. Open EtreCheck, and before running the report, be sure to check “Allow full Drive Access” at the bottom of the EtreCheckPro window.
  4. Run the report, and put it in a post, as seen here: https://discussions.apple.com/docs/DOC-250000211. We will then examine the report for issues in your Mac.
