![]() ![]() I'm still on Catalina as my trick to get the card not to overheat is to use VGTab, and basically play with the power play tables. It's a blower style card, and does not feature a fan stop mode (I confirmed this by running it in Windows and the fan never turns off), but in macOS until I really push the GPU it doesn't spin the fan up at all. ![]() Having something like iStat Menu is completely central to how you use your Mac or any PC with Windows or Linux, where similar programs exist, efficiently.I've had a similar issue on my MSI Airboost Vega 56. IStat Menu allows you to act in time, before a small problem becomes a big problem, when you're watching that RAM usage just going up and up for some task you're running in the background or that your disk space is dwindling to zero. The idea of not knowing why the Mac is slow is pretty much like not having a speedometer in your car to know how fast you're going or not having a gas gauge and the only clue you have that you need to put on more gas, is that your car sputters to a halt. ![]() It's simply easier to monitor and control your Mac, by quitting programs that can quickly become resource heavy, like 3D modelling software, renderers, simulations, but also webbrowsers that go on crazy websites, before they run your Mac dry of resources, locking it up and forcing you to reboot, because you're out of paging space and RAM. I don't get that information from the simulation software itself, and I can't get that from Activity Monitor either. This can often tell me if the SSD is paging intensely and that the simulation has run out of memory and I need to tune it to use less memory. Here's a wild one: Sometimes the CPU graph behaves in a way that is very specific, so I can actually tell when some fluid simulation software I have is doing a specific thing, just by looking at particular spikes, spacing between spikes and the distribution between user and system CPU consumption. And sometimes OSX, will actually page so heavily that I, untimely, do run out of disk space, meaning the computer completely stops functioning and I must forcibly reboot, or alternatively, wait 30 minutes before it comes back again. A simple glance at the disk space meter will do. You can also quickly and easily tell, if your webbrowser is causing trouble on specific websites, just by going on a website and quickly glance at the CPU graph and see if it's moving up a little.Īm I running out of disk space? No need to get hold of a Finder window. I've used this to control a Macbook Pro with broken fans, so it made less noise. Did my render complete in 2 hours or 7 hours, while I was away? Is the CPU running hotter during the day than at night? Am I gaining or losing disk space? ![]() IStat Menu also stores resource consumption information over the last hour, the last 24 hours and over 7 days, so you can tell, when the computer consumed more resources recently and for how long. I know what's happening, and I let it finish. What's it doing? I look in the menu for disk activity and a very specific program is churning away on my second USB drive and has been doing that for 6 minutes. It's a great way to tell when programs are being nasty with the resources. Why is the computer slow as hell with the display stuttering like crazy? A quick glance shows that the GPU memory has been consumed by Substance Painter. iStat Menu shows GPU usage and GPU memory usage for all GPUs connected to the system in one single glance. Then I monitor the GPU performance: Using CUDA and OpenCL programs, it's often difficult to tell whether the GPU is actually using those frameworks through the programs themselves. I've used this to improve the cooling of my Macbook Pro with better and quieter external fans, so the machine can run quietly 24/7. You can tell, if your network is being used unnecessarily or if it's running slower than usual, and it displays every single temperature sensor in the machine in a menu, so you can tell which part of the computer is hotter than other areas. iStat Menu lets you know this immediately by showing spikes and also brings you all the clues immediately as to why it's happening, so you can do something about it in an intelligent way rather than just hold down the power button or spend a few seconds troubleshooting a problem instead of a whole afternoon. OSX isn't infallible and indeed, when you run programs that are resource hungry, they can bog down the Mac, both in CPU, disk and RAM resources. ![]()
