Macbook Air really slow and running hot with OSX 12.3 update

My laptop was very slow just before the update became available so I updated because it seemed to fix the problem in the past. This time the problem seems to be with Safari which is so slow that I had to switch to Firefox to get anything done. Also the fans are running about 75% of the time vs 5% in the past. Since moving to Firefox the issue has subsided. Does anyone know what may be the cause and how to get around it? I would like to get back to Safari if possible.

MacBook Air 13″, macOS 12.3

Welcome to the Apple Support Communities.


First, take a look at:


If the issue persists, then 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 shown here: How to use the Add Text Feature When Post… - Apple Community. We will then examine the report for issues in your Mac.
