• The upgrade pace of El Capitan lags behind Yosemite
• A series of problems are found in OS X El Capitan
• Downgrade from El Capitan to Yosemite in two methods
OS X El Capitan, Apple's latest Mac operating system, seems like a modest update after last year's Yosemite release. OS X El Capitan of course brings some very interesting new features that users are eager to try out but that does not mean the new OS is mandatory.
According to the data showed in below chart from Net Applications, El Capitan, released on the last day of September, it had been installed on 38% of all Macs 61 days later. Yosemite (with a user share of 44.5% at the end of December 2014), trumped El Capitan (user share of 38% at the end of November 2015). Besides, the latest OS El Capitan release by the Cupertino-based tech giant currently has an average rating of 2.5 out of 5 stars on the App Store, which is supposed to be the lowest rating for an Apple OS version so far.
After upgrading to El Capitan, a series of problems occur, which are quite annoying.
1. The Update Time
Usually, the length of time to install the El Capitan update is too long. Users state that it takes a minimum of an hour to get one update completed and they are likely to stuck on a gray screen during the OS X El Capitan installation.
2. Problem with Third-party Apps
After upgrading to OS X El Capitan you may experience apps that crash or that simply do not work at all but used to run properly on the previous OS before the upgrade.
3. Bluetooth Problem
After upgrading to OS X El Capitan, you may have seen odd Bluetooth connectivity issues with the Apple Magic Trackpad.
4. Deletion Problem
Many users are complaining about similar files deletion related problems after upgrading to the new OS X El Capitan. You can learn more in “Can’t Delete Files? Wanna Recover & Restore Deleted Files? All ‘Delete’ Related Problems in El Capitan”.
5. The Underperforming Spotlight
Spotlight has gained even deeper integration with OS X and web services. The search software is supposed to yield multiple results quickly, but users have reported that it sometimes doesn't and sometimes gives only limited data.
6. Microsoft Office 2016 Problem
Some users complained that they’re unable to do any work due to Office 2016 crashing continuously and/or the system freezes after upgrading to El Capitan.
7. Login Fails
After the final reboot of the upgrade process, the user is brought to the logon screen with an account listed as "Setup user" and prompted for a password to authenticate. Regardless of the password entered, the password box shakes "no," and the user is not able to login.
8. Wifi Issues
The wifi problems are in the form of dropping connections or strangely slow speeds, which makes many users crazy.
Though Apple faithful want users to focus on the benefits of upgrading to El Capitan, you can downgrade El Capitan to Yosemite if you aren’t too fond of it. Beyond any doubt, the multiple El Capitan bugs are going to be addressed by Apple in the near future. Sometimes, however, the user needs full functionality of their machine right here and right now.
