When I logged in to the computer as another user (which is rarely used) Safari loaded quickly.
Any additional thoughts?
You're welcome.
The fact that Safari launches immediately under another user indicates that there is likely some software conflict going on in your regular account.
Start by making sure your macOS Sequoia is updated to 15.7.3, (update, not upgrade) the current release. If you are not running that version you may have missed a bug fix along the way. Update macOS on Mac - Apple Support
Also make sure that you have downloaded the latest update for the Safari app. You should be running version 26.2 .
If both of those versions match what is running on your Mac, then I'll ask you to please run an EtreCheck evaluation of your Mac and post the generated report back here in a reply. EtreCheck is a safe and highly regarded utility from a trusted developer and respected ASC contributor. The report EtreCheck generates will not include any personal info. It simply gathers specifics about hardware performance and installed software that might be in conflict with the OS and eliminates us having to play '20 questions' to get to the heart of some things.
Please navigate to EtreCheck.com to download the utility. Be sure to Allow Full Disk Access when you install the app. Once you’ve run the app and created your report please post it with your reply to this message.
Please note you must upload the full report. To see how, please click > How to use Add Text when posting… EtreCheck Report.
We’ll use your EtreCheck report to look for the things that may be causing your problem and advise how to correct them.
