Having used Windows computers for many years and have since been converted to Apple Mac, we have experienced both operating systems for a good amount of time. We currently run Mac OS X 10.8 Mountain Lion on both MacBooks and an iMac, but also have Windows 7 on two touchscreen computers. Both operating systems suffer from crashes although Mountain Lion has a better track record so far, and certainly is not plagued by the viruses and malware you’ll find with Windows.
We have experienced a few crashing problems with Mountain Lion since it launched, and this includes Safari crashing sometimes when you open a new tab via clicking a link and selecting “open link in new tab“. It is worth noting that when you do this a second time by reopening Safari right after a crash, it doesn’t happen.
The Apple discussion forums are filled with issues being reported by users, which is expected with any new OS and this includes Mountain Lion. There are two clear crash problems affecting a lot of users, and this includes the above Safari problems and also Mountain Lion crashes when resuming from sleep. Some people solved this issue by turning off their Wi-Fi on MacBooks before closing the lid, and also some iMac users found that making sure Bluetooth is turned off stopped a crash when the computer sleeps.
Have you had any crashing with Mountain Lion or default installed software? You can see the forum entries here for Mountain Lion crashes after it resumes from a sleep, and also some other Wi-Fi issues are being discussed in this posting.
If you have not installed Mountain Lion yet then you might want to read some reviews, which can be seen via this article and clearly show the overall Mountain Lion performance is extremely good for the majority.
