I’ve written a few tech tip articles for Mac OS X, but hopefully you’ll find this list of common Mac OS X problems and solutions helpful.
GMail Bug In Default Mail App
If you use the default Mac Mail app, you might have run into some issues when setting it up for your GMail account or Exchange. Try these steps to get it working:
1. Open default Mail app on your El Capitan, then from the “Mail” menu and go to “Preferences” option.
2. Go to the “Accounts”, and select the email account that has problems, then click on the “Advanced" tab.
3. Find the box named “Automatically detect and maintain account settings”.
4. Now check or uncheck it – then re-launch Mail app.
Mac Won’t Start
Nothing can be more frustrating that going to your Mac only to find out it won’t boot or start. Here are some common troubleshooting tips:
1. Make sure that you have a good connection from your Mac to the wall outlet by confirming the power cord.
2. If the wall outlet is working and you still have no power, try another power cord or adapter. If it works you may need a replacement cord or adapter.
3. Disconnect all accessories that are plugged in to the computer.
4. If you recently installed any of the solid drive, hard drive, make sure that they are installed correctly and are compatible with your computer. If it is possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.
5. If your mac still won’t start up after trying each of these steps, you may need to visit an Apple Store.
