I've got a real strange (and frustrating) issue. Hopefully someone can help.
I've always liked Safari and it has always performed well. But ever since I upgraded from Lion to Mountain Lion, Safari will freeze the computer about once a day. I cannot find a specific repeatable action. But this morning, it happened when I was filling out a Godaddy customer survey. Clicking radio buttons. But other times, it will be doing something else. Symptoms are always the same: The mouse keeps moving normally but I cannot click on anything. The computer does not respond to anything on the keyboard. The only way to get out of it is to press and hold the power button.
Today I only had one window and one tab open in Safari. The computer had been restarted (after a similar crash) yesterday and I only had Photoshop cs6, Notes, TextEdit and Mail opened. So there should have been plenty of RAM free. My internal HD has 500 gigs available so plenty of room there.
I do not have any added extensions or plugins for Safari or for the system. It's all pretty stock.
iMac 24-inch Mid 2007
Processor 2.4 GHz Intel Core 2 Duo
Memory 6 GB 667 MHz DDR2 SDRAM
Software OS X 10.8.1 (12B19)
Safari Version 6.0 (8536.25)
I've checked on this board but have not found anything that helps in my case. This is not the "Safari is slow to open pages" issue. I've been using Macs for 20 years and this is really the first time I have had a consistent crash situation. Things are usually pretty bulletproof here. My 2007 MacBook Pro 13 works flawlessly with the same sofware configuration.
Thank you for any hellp at all.
