OSX audio stopped working

· ·

I have this issue regularly where the OSX audio stopped working on my Macbook. I am using High Sierra right now but had the same problem with Sierra. Not sure what is causing the problem, and not sure how to prevent it from happening. I have figured out though how to solve it, and as occasionally I find myself searching for the solution I figured I would quickly document it on my own blog. If your audio has stopped working you can simply stop the service responsible for it.

For me the following works solving the problem:

sudo killall coreaudiod

For me audio comes back again automatically almost instantly, some actually have reported they need to start the service again

sudo launchctl start com.apple.audio.coreaudiod

I hope this helps others as well as running into the same problem. If you have and you solved the problem in a different way please leave a comment.

Powerpoint for Mac switching resolution?

· ·

I’ve had this issue for a long time. Whenever I would open PowerPoint and present using a projector all my diagrams and screenshot would show up fuzzy. Even if I would set up the screen configuration to be optimized for the projector it still would not look great. The funny thing is that I always have my screen setup in “mirror” mode, and this week I noticed that when I switched between my regular screen to Presenter Mode on PowerPoint that the resolution would change.

Apparently when you use presenter mode with PowerPoint on a Mac it sets the screens in “extended mode” automatically. By default it then seems to optimize for the Mac screen automatically, which usually does not work well for the projector considering most are low resolution devices. I disabled the Presenter Mode option next, and when I turned off presenter mode in PowerPoint it worked fine. You can switch it off in Preferences under Slide Show:

I normally don’t blog about this kind of stuff, but as I hardly was able to find anything useful about it anywhere I figured I would share it with the world.

Iomega PX6 / PX4 update that enables Time Machine to work properly

· ·

Just wanted to point out that if you flash your Iomega PX6 or PX4 with the latest firmware, 3.1.14.995, it will actually enable you to do Mac OS X (Lion / 10.7) Time Machine backups and restores again… I discovered it by accident as somehow Iomega did not list it in the release note and they did not update the KB article which explains that it doesn’t work. Anyway, it works again… Simple download and upgrade of your PX6/PX4 firmware will do the trick, at least it did for me.

Enable TRIM on OS X 10.6.7

· ·

Thanks to Jason Nash’s article I managed to finally get TRIM enabled for my SSD on my MAC. The procedure works great, however when you have a dual SSD setup like I have (booting on a 120GB Intel and running my VMs on a 256GB Kingston) it doesn’t work as replacing the identifier leaves you with 1 SSD without TRIM support. I googled around for a bit and found this article by Oskar Groth. Oskar made a nice GUI tool that enables TRIM for you on all SSDs that your Mac contains! Be aware that this is a hack and there is no support whatsoever for this. So why would you add it? Well look at the test that Jason did, and I also did some testing and the preliminary findings are that it vastly improves your performance!

Windows 7 on a Mac!

Most people will agree that Apple products have certain kind of coolness. Most people will also agree that VMware Fusion has a certain kind of coolness, especially the Unity feature. Combine this coolness with the Windows 7 beta and you’ve got one hell of a combo.

I can imagine you don’t want to spent a lot of time on figuring out how to install Windows 7 within a Fusion VM, lucky you…. Team Fusion wrote an extensive blog article on how to install Windows 7 within a VM, and not only text and screenshots but also a video. Team Fusion is definitely one of the most active bloggers Team within VMware, keep up the excellent work guys! Now, check out the full article, even if you don’t own a Mac! And while you’re there Digg It!
