A Synopsis to Common MacBook Issues & Fixes

MacBook Issues

Even though rarely, Macs also encounter technical issues that cause frustration and productivity loss. The major concern related to any performance glitch is data loss, which everyone wants to avoid. Hence, learning the workaround for common MacBook problems can help you bring it back to its normal state. 

Let’s move to common Mac problems and their resolutions. 

Problem 1: Search Marquis Intrusion 

Solution: Install Antivirus & Delete Suspicious Apps

A majority of users have the impression that Apple computers, including Macs, iMacs, MacBook Pro, and MacBook Air, are immune to viruses and malware infections. As a result of this belief, users start downloading all kinds of files that become the entry point for viruses. 

Search Marquis is one such virus that redirects web traffic to It’s a landing page with a search box that redirects all your searches to Bing. When you search anything on this website, the query travels through dozens of domain names that include mainly advertising platforms. 

If you find your web browser redirecting to Search Marquis, install an antivirus application and run a deep scan. In addition, delete all the suspicious apps that might be affecting the CPU processes by navigating to the Activity Monitor. 

Also, remove any additional login items that run automatically each time you start your computer from Users & Groups under the System Preferences. Moreover, scan your computer to check any leftovers, and delete Search Marquis extensions (if found). 

Go to to find the detailed procedures to get rid of Search Marquis and other potential threats from your Apple computer. 

Problem 2: Power-Related Issues 

Solution: Reset SMC, PRAM, or NVRAM

SMC, PRAM, and NVRAM are the major components of Mac computers. They are primarily responsible for controlling startup functions in Mac, iMac, or MacBooks. The latest Mac computer, NVRAM (Non-Volatile Random Access Memory), replaces the PRAM (Parameter Random Access Memory).

SMC is responsible for controlling low-level functions and power-related settings on Intel-based Macs. NVRAM performs the same operations as PRAM. NVRAM in computers is responsible for handling and controlling startup disks, power settings, speaker volume, time-zone information, screen resolution, and more. 

Resetting SMC can help solve most of the power-related issues in Macs and MacBooks. Other functions that SMC controls include:

  • Battery management
  • Thermal management
  • Ambient light sensing 
  • Sudden Motion Sensor (SMS)
  • Battery status indicator lights
  • Keyboard backlighting
  • Status indicator light management

Shut down and then turn on your Mac computer while holding down the Shift + Control + Option keys. Next, release all the keys slowly to let your Mac computer boot. 

Problem 3: Startup Disk Full Error

Solution: Clean Up Hard Drive

A startup disk on Mac is the HDD partition where macOS, apps, files, and other data are installed. Over time, the startup disk starts to saturate with data, data, and data, which needs to be deleted. The more apps you are installing on your Mac, the more will be the cache and temporary files stored on your hard drive. 

If your startup disk is full, you will get an error message saying “Your disk is almost full”. In that case, you will need to clean up temporary files to make space on the hard drive for other important data. Temporary files are of different types, such as the application cache, browser cookies, outdated system logs, document versions, and more. 

You can delete temporary files manually from the Finder window. Make sure to close or quit any open apps before you proceed to clear the temporary or cache files. Browse the hidden folder names as ~/Library and find out the files that are sitting there doing nothing. 

Outdated system files and temporary storage on system storage media make the computer slow and sluggish. This calls upon the need to clean the storage manually or by using third-party applications. Even the most powerful Mac models demand regular cleaning and optimization. 

How to Identify Technical Issues in Your Mac Computer?

Spinning Beach Ball: The spinning beach ball is probably the first sign (in most cases) that indicates your computer’s performance is at stake. So, the first step that you can take towards preventing your computer from falling ill is navigating to the Activity Monitor to check if all the apps and programs are working appropriately. 

Resource-Hungry Apps: Launch Activity Monitor from the Utilities folder inside the Applications under Apple Menu. There you can see the apps that are impacting your system performance by detecting how much memory resources and CPU power each app is consuming. You can detect any suspicious apps and remove them right away. 

Apps Not Downloading: If you are not able to download or open any application on your computer, your computer might be encountering a technical issue. Check your system’s hard drive and keep track of the available space. As a rule of thumb, the hard drive should never fall under 15% of the overall storage, else the performance will suffer. If so, try to delete redundant data.
