I had this problem once with my iMac and I didn’t know wha to do. I did some research online and did the diagnostics by myself and found out that hard drive has gotten bad. I bought a new hard drive and installed it myself. Moreover, I made USB bootable for MacOS and install it on my iMac. Now my iMac is working better than before.

iMac GPU Issue

If you see flickering, shacking, and stripes on your iMac screen, it’s most likely a GPU problem. When the graphics card inside the iMac cannot provide enough power to display on iMac, it usually shows vertical stripes in the iMac screen. Sometimes, your iMac works even if the screen is flickering, but most of the time your iMac will be in a boot loop. It tries to turn on eventually goes off.

I has one customer who has that problem with their 2013 iMac. The iMac was working with a little shaky screen, after using it for 5 minutes it eventually shuts down. We solve this problem by replacing the graphics card. There are some applications like Heaven which you can use to check your iMac graphics. When you run heaven program on your iMac, it rung on very high graphics, if your iMac had GPU issue your iMac will go off.

Very Slow iMac

This is also one of the most common problem among iMac users. It’s very frustrating when iMac takes very long to boot up and responds very slowly. In this article I will be talking about the reasons behind slow iMac. Below are the list of reasons that can cause slow iMac.

  • Old hard drive
  • Bad system memory
  • Old version of MacOS
  • Full storage
  • High graphics games and programs
  • Virus on the system
  • Bad logic board (very rare)

I fixed a lot of slow iMac computers for my customers and found out that almost 80% of the time the problem is iMacs storage. When I see slow iMacs, first thing I do is try to boot it from the external bootable SSD. If it works faster with the SSD, the problem is storage. Most of the time replacing hard drive with SSD solves the issue. Sometimes updating MacOS also makes iMac faster. Moreover, upgrading system memory also a good alternative for faster iMac.

When your iMac has any issue you can try to repair it yourself by using the steps above. If it doesn’t solves the issue you can take your iMac to Apple store for repair. Furthermore, you can also try local computer repair shops near McKinney Texas.
