Get Rid of Log-In Items
Your Mac could have become clogged up with various log-in items that impact its boot performance. It’s worth checking new log-in items occasionally to keep your MacBook in good health and run at optimum performance.
1. Click the Apple menu on the system menu.
2. Select Preferences.
3. In the new screen titled System Preferences, you’ll find a couple of system settings and configurations.
4. Click the Users & Groups icon.
5. Click the Login Items tab.
6. One by one disable the log-in items displayed on your screen.
Unplug Peripheral Devices
A peripheral device is an electronic equipment connected by a cable, plugged in to the computer. Are you one of those users who keep their peripheral devices plugged-in for no reason?
Unplug any external peripheral devices such as an external hard drive, USB Wi-Fi, printer, scanner, cordless mouse when not in use. Mac takes time recognizing these devices as it loads corresponding drivers at the boot interval.
Upgrade to an SSD
An SSD stands for Solid State Storage, a type of storage drive that can read/ write your files faster than an average Hard Drive. The random access time of a Hard Drive – which uses a physical spin, is up to 10 milliseconds whereas an SSD takes merely 0.1 milliseconds to perform a similar operation. Various Mac editions such as iMac, Mac Mini and newer MacBook’s are prone to come up with pre-equipped SSDs. If you’re still using a standard HDD, it’s worth upgrading to a larger sized SSD.
Upgrade the Computer Memory
Adding up a decent amount of Random Access Memory (RAM) – an integrated circuit memory chip, can make your Mac more responsive and load quicker. It’s worth a shot.
Dying SSD? Test it now
Unstable voltage, shutting off a MacBook while it’s in use, can lead to serious disk errors, and at worse, a dying SSD or a hard drive. Thankfully, Mac comes with a pre-build tool called Disk Utility, much similar to Check Disk in Windows that helps users find and diagnose disk errors up to some level. Serious disk errors may, however, require urgent attention. In such cases, you might want to buy a new SSD in order to prevent severe data loss.
1. Click the Go menu, select Utilities.
2. In the Utilities folder, click the Disk Utility.
3. Select your SSD or HDD displayed in the left hand side panel.
4. Click on the First Aid icon.
5. A confirmation prompt will appear on your screen. Click Run.
Move Less Frequently Needed Files to USB Stick
If there isn’t a decent chunk of free storage space available, move less frequently used files to a USB flash drive or an external hard drive to reclaim lost storage space. You can alternatively upload those files to free cloud servers online. Permanently remove any files you no longer need, such as, unwanted downloads. Another obvious way to free up your space is to empty the Trash contents regularly.
Skip User Log-in Screen
Unlike Windows, Mac prompts for a user password every time a user turns on his/ her computer. Skip the user password prompt and force Mac to automatically log-in every time after post-boot interval.
1. Open up the Users & Groups dialog. (Refer Steps # 1-4 under Get Rid of Log-In Items)
2. Click the Lock icon at the bottom left with the text Click the lock to make changes.
3. Enter the administrator password. Click Unlock.
4. Click on Login Options in the left panel.
5. In the Automatic Login drop-down box, select a user profile you would like to automatically load.
6. Enter the user profile password to confirm.
Choose Not to Open Previous Windows/ Apps after System Start-up
One of the coolest features in Mac is its ability to reopen any programs and windows that you left opened in your previous session. Although this feature can be quite helpful and convenient for many, it sometimes severely deteriorates the boot performance.
As usual, when you shut down your computer, be sure to un-check the box named Reopen windows when logging back in, and then click Shut Down.
Delete Unneeded Fonts
Mac comes with a set of different fonts with various languages within a type family. Uninstall some of the fonts you never use, especially the languages you do not know. It can free up precious disk space and make MacBook boot faster.
1. Open the Applications page. (Go | Applications)
2. Open the Font Book.
3. The list of all fonts will appear on your screen.
4. To remove a font, right-click it and select the option Remove <Font Name> Family.
5. To search and remove duplicate font entries, right-click a font, choose Resolve Duplicates. If no duplicates are found, No Duplicates Found notification will appear on your screen.
Delete Corrupted Preferences
Preferences files contain rules that define behaviour of an application. A preferences file can corrupt when an application unexpectedly crashes. Delete the broken up preferences files as shown under:
1. Click the Go menu, select Go to Folder.
2. Type the following:
3. Click on Go.
4. Right-click a file named LoginWindow.plist and select Move to Trash.
Two of the impressive features in Mac OS Sierra are its transparency effects and animations. If you’re using an older MacBook with newer OS, it’s likely to heavily stress your hardware. You might want to lighten the system by disabling such resource-consuming features.
1. Open up the Preferences page (Apple | Preferences).
2. Click the Accessibility icon.
3. Click the Display icon in the left hand side panel.
4. Check-up the box Reduce Transparency.
Check for Persistent Issues
Mac comes with a tool, System Report that reviews general health of your computer and highlights areas that require urgent attention. This tool, located in the About this Mac dialog, can be a great help to identify which hardware/ software components are dragging down your computer’s start-up performance.
1. Click the Apple menu on top, select About this Mac.
2. Click the System Report.
