Mac mini Mid 2010 video issues

[lhoffstadt]

hi everyone, I have a Mac mini Mid 2010 running 10.14.1 with a Nvidia Geforce 320M with some videos issues, it usually happens when I'm watching videos on YouTube or viewing a webpage or email with a lot of pictures or animated graphics on it.
When I work in Photoshop or Lightroom I don't any issues. I took a picture of the issue that I will upload shortly.
Sometimes the issue get resolved by it self or sometimes I have to do a hard reset because the OS gets unresponsive.

Is this a known issues or has someone else experience this?
I have the Mac Mini for about 3 years or so and I just start experience this issue maybe 1 month ago.

Thanks for any recommendation on this.

In System Preferences / Accessibly / Displays, is "Reduce Transparency" ticked?

I will check and get back to you. I just uploaded a picture of the issue I have

Also, are you sure its a Mid-2010 Mac Mini? As officially that model isn't supported by Mojave (10.14).

I will check and get back to you. I just uploaded a picture of the issue I have

If you find "Reduce Transparency" is ticked. Try un-ticking it and then seeing if you can replicate the issue.

yes, the previous owner install and unsorpoted OS in this Mac Mini and I have not change anything since I have it

Perhaps this is why there's an issue.. Try the "Reduced Transparency" suggestion, if that doesn't work, I'd recommend downgrading it to it's supported macOS version High Sierra (10.13).

I wouldn't trust it with an unsupported OS.

If it had High Sierra (10.13) installed and that happened I would say bad RAM or the solder bonds on the infamous nForce chipset is failing.

thanks, I will give it a try

hi, any recommendation on where to download high sierra so I can downgrade the OS to his original version that is supported for this Mac Mini? thanks a lot

You could try Internet Recovery. Hold down Option-Command-R at startup and it should boot into High Sierra Recovery.

Alternatively you could try downloading High Sierra here: https://support.apple.com/en-us/HT211683

 

[lhoffstadt]

thank you very much for your help

So are you back on High Sierra and are things running smoothly?

If you have an internal HDD in the machine ou could speed up the machine by putting a SSD in or if not comfortable with that you could try booting off a FW800 SSD. It would make the computer feel faster.

 

[lhoffstadt]

the issue continues with the weird graphics glitches some times, so I think I will install High Sierra during the weekend and yes, it is a great idea to put an SSD to allow the Mini to run smoother.
Thanks

I'm using an enclosure with both USB3 and FW800 connections with a 2009 Mini. Using the FW800 at the moment but if I retire the older Mini I can then use the USB3 cable with a newer Mac. Pre-2012 Minis don't have USB3 and pre-2011 Minis don't have Thunderbolt. So FW800 is the best external booting option for the 2009 and 2010 Minis.
