At Advanced Computers, we regularly see MacBooks and iMacs brought into our Rosedale and Penrose workshops because they feel slow, unresponsive, or cluttered. In many cases, the issue is not hardware failure but settings, storage management, or background processes that have built up over time.
Before booking a Mac repair, there are several macOS adjustments you can safely try. These steps can improve performance and productivity, especially for home users, students, and small businesses across Auckland who rely on their Macs every day.
1. Check Storage and Clear Unused Files
One of the most common causes of slow performance is low storage. macOS requires free space to run efficiently.
Go to System Settings and review your storage usage. If your drive is close to full, remove unused applications, old downloads, and large media files. Cloud storage can help reduce local file load, particularly for businesses working with design files, video, or photography.
If your Mac still runs slowly after freeing space, it may indicate a failing drive or ageing hardware. We often see this in older MacBook Pro models brought into our North Shore branch.
2. Manage Startup Applications
Many applications automatically launch at startup, which slows boot time and overall responsiveness.
Review login items in System Settings and remove anything unnecessary. This simple step can significantly improve startup speed and daily performance.
In our Auckland workshops, we frequently find multiple background apps running without the owner realising, particularly on machines used for remote work.
3. Keep macOS Updated
Keeping macOS current ensures you receive performance improvements and security updates from Apple. However, major updates should be approached carefully on older devices.
If you are unsure whether your Mac can handle the latest macOS version safely, it is worth getting professional advice before upgrading. We assist customers across Auckland with upgrade assessments to prevent compatibility issues.
4. Use Activity Monitor to Identify Resource Hogs
If your Mac feels sluggish, open Activity Monitor and check which processes are using the most CPU or memory. Web browsers with many tabs open are a common culprit. For business users in Auckland running accounting software, CRM platforms, or design tools, excessive memory use may indicate the need for a RAM upgrade rather than a full replacement.
5. Optimise Finder and Workflow Tools
Simple organisation improvements can also boost efficiency:
- Use Finder tags to categorise files
- Create Smart Folders for ongoing projects
- Use Spotlight search to locate documents quickly
Built-in apps like Notes, Reminders, and Preview can reduce reliance on third-party software. Preview, in particular, allows PDF annotation and signing without additional downloads. These small workflow adjustments can make a noticeable difference in day-to-day productivity.
When Software Fixes Are Not Enough
If you have tried these steps and your Mac still freezes, overheats, or crashes, the issue may be hardware related.
Common problems we see at Advanced Computers include:
• Failing SSDs
• Battery degradation
• Overheating due to dust buildup
• RAM limitations
• Logic board faults
Our technicians provide diagnostics at both our Rosedale and Penrose locations in Auckland. We repair MacBooks, iMacs, and other Apple devices, offering component-level repair where possible.
Local Support You Can Rely On
As an Auckland-based Mac repair centre, we support students, professionals, and businesses who depend on their Macs for work and study. Whether it is a simple performance tune-up or a more complex repair, we aim to extend the life of your device where practical.
If your Mac is slowing you down, you are welcome to book a repair online or contact our team for advice. Sometimes a quick adjustment is all that is needed. In other cases, early intervention prevents more expensive damage later.
Keeping your Mac running efficiently is not only about productivity. It also protects your data, reduces downtime, and helps you get better value from your device.
