Recently, several mac users report some problems after they update to the new OSX El Capitan. Here is problems that may appear on your side and how to fix it :
1. Spotlight problems
The spotlight sometimes didn't show results that you expected. First, you can try to deactivate and activate the spotlight again. To do this, Go to System preferences => Spotlight. Second, you can open the Search Results tab to see whether the spotlight index is correct.
If the method above doesn't work, Go to terminal, run command mdutil -Ea to delete the index. Next, type mdutil -ai off to deactivate spotlight. Finally, activate the spotlight again using command mdutil -ai on.
2. Wifi problems
If you found problem with your wifi connection. First, you can try to restart your modem or wifi router and see if that works. If the problem persist, Check wifi settings in your mac. To do this, Click wifi in menu bar. Choose Turn Off Wifi. Next, open network preferences and click Advanced button. Delete the wifi SSID that you have problem with and try to connect again with that wifi.
3. Mail problems
I personally often have problems with mail app. Sometimes, the app having issues in sending and receiving email. If you have same problem, you can try to turn off your wifi and internet connection and deactivate your mail account by going to Mail => Preferences => Account.
Turn on your internet connection and activate your account. If you have more than one account, I suggest you to activate it one by one.
4. Bluetooth problems
If you have problems with your bluetooth, the first thing you can do is to unpair your bluetooth and try to pair it again. If the problem still appear, try to connect it to your mac via usb port and eject it directly. Turn your computer off, wait for a moment and then turn it on again.
Sometime, you may still have the problem, You can try to reset the controller setting. To do this, Follow the steps below :
- Turn off your mac
- Press command, option, P and R until the screen turn into grey.
- Hold it until your mac boot twice.
- Release the button.
After doing this, you need to reconfigure your timezone, screen resolution and speaker.
