Just like Windows, Mac OS can also be restored to a previous state. Everyday tasks, such as software downloading, installation of updates, changes in settings, etc. influence Mac’s performance and, usually, decrease it’s speed gradually.
Luckily, Mac OS has an inbuild System Restore feature, which is an equivalent to Windows System Restore Point. The feature is extremely useful if Mac gets slow, starts freezing or doubtful system errors start emerging. It’s not difficult to restore your Mac to the previous date. The system has a built-in back-up feature known as Time Machine.
To restore the system, you’ll have to set up the Time Machine. If you haven’t set it up yet, unfortunately, you won’t be able to reset your Mac OS to the previous date because the system does not have the copy of its previous state.
Step 1. Set up Time Capsule
Time Machine on Macs is a great tool that allows creating backups of your files. To set up Time Capsule, you’ll have to use an external driver, which has free space that would be sufficient for all data from your internal drive.
First of all, connect an external hard drive, which is connected to a USB, Thunderbolt port or FireWire. The external hard drive connected to the USB port of an AirPort Extreme base station on your network also fits.
Once you connect an external hard drive to your Mac device, you may receive a confirmation window saying: “Do you want to use the drive to back up with the Time Machine?” Select Use a Backup Disk to proceed.
In case you want some extra security, you can select “Encrypt backup Disk” by which you will put a password on the created backups. Sometimes, connected hard drive doesn’t trigger confirmation window. In this case, you should perform the following steps:
- Select Apple menu –> System Preferences –> Time Machine.
- Select Backup Disk option.
- Select an external hard drive that you attempt using (listed above) and click the Use Disk option.
- To ensure security of your data, click Add or Remove Backup Disk
Step 2. Back up data using Time Machine
Once Time Capsule is set up, it starts creating backups for the past 24 hours and daily backups for the previous month automatically. In case you want to create backups right now, you have to select Back Up Now on the Time Machine menu.
Step 3. Restore Mac OS
As soon as you enable Time Capsule and create backups with Time Machine, you can use the option to restore the system to the previous date. For this purpose, you have to launch OS X Recovery Tool:
- When you boot up your system or restart it, click Command key + R simultaneously to open OS X Recovery Tool.
- Select Restore from Time Machine Backup.
- If you have created more than one backup, select the one that has been created before your Mac errors occurred or before it got slow.
- Finally, wait for the system to restore. This may take a while.
NOTE: If you don’t have a Time Capsule and can’t create backups, then the only solution to restore your Mac to the previous state is to reinstall it.
By the way, you can also try using a Mac optimization tool, for example, MacKeeper. This program has been developed for increasing Mac’s speed and overall performance, so if the problems that you encounter are not too big, optimization tool may be a great solution.
