Although this should be consistent within any given Mac, it doesn’t compare well between different GPUs. % GPU is a similarly rough measure of GPU activity. It’s not known whether this allows for the percentage of time in active residency, but it makes no allowance for different frequencies or core types, so mustn’t be over-interpreted. Unfortunately, Activity Monitor doesn’t provide any information on core frequency, which is only available using the command tool powermetrics.ĬPU Time is the total available processing time that has been used by a process. A P core with 100% active residency at a frequency of 3 GHz processes instructions at three times the rate of the same P core at 100% and a frequency of 1 GHz, yet both will be shown in Activity Monitor as being at 100% CPU. Although the former affects some Intel processors, both are most significant on Apple silicon. Thus, processes totalling 100% CPU on my eight-core Intel CPU mean that its cores spend 700% idle, and there’s still a total core reserve of 1500% allowing for the maximum achievable with hyperthreading.įor cores with variable frequency, no allowance is made for any change in core frequency, nor for different types of core.

The counterpart to % CPU is that the percentage not accounted for in % CPU is spent idle.

This is complicated for Intel processors with support for hyperthreading, which adds a further 100% for each core, resulting in full % CPU rising to a maximum of 1600 for those same eight cores. If your Mac’s chip has 8 cores in all, then as each can run to 100%, when all eight cores are fully active, the total % CPU comes to 800. Total active residency is measured for each core, then added together. Thus, in a given 10 second period, if 25% of the cycles are spent processing WindowServer code, the % CPU for that period is 25%. It seems to be based on the active residency of each core, that’s the percentage of processor cycles which aren’t idle, but actively processing threads owned by a given process. It’s also misleadingly inaccurate on Apple silicon chips. % CPU is a rough measure of the amount of time on the CPU cores that a process has run, but isn’t a true percentage out of a hundred. To help you understand and compare them, I’ll try to explain what I think the less obvious numbers mean. Now there are also Apple silicon Macs, some of the figures don’t quite tally across architectures. When all Macs were Intel, even if we couldn’t necessarily define some of them, it wasn’t hard to work out roughly what each meant.

Press and hold the Shift key, then click Continue in Safe Mode.Activity Monitor provides many different numbers for aspects of your Mac’s performance.

Choose your boot drive (usually Macintosh HD).

Now, press and hold the Power button until you see the ‘Loading Startup Options’ page on your screen.

You’ll know your Mac is completely shut down when the screen is black and indicator lights are off.

Open the Apple Menu and click on Shut Down.

Here’s how you can boot Macs with Apple Silicon in Safe Mode: This also checks your startup disk and resolves any issues.

When starting your Mac in safe mode, it will prevent startup items and third-party software from loading. You can boot your Mac in safe mode if there are still missing columns in Activity Monitor. Go back to the Activity Monitor afterward to confirm if the problem is solved. Software updates can take several minutes to complete.

#ACTIVITY MONITOR MAC OS UPDATE#

The update progress bar might also appear to be stuck.

Your Mac can restart several times while installing the update.

You can just leave it plugged into the wall outlet during the update.

If you are using a MacBook, make sure that your battery is at least 50% charged.

This should force your Mac to generate a new plist containing factory settings for the Activity Monitor. If the Activity Monitor is still missing some columns, reset your preference file by deleting it. When a plist gets corrupted, it can cause problems with the application it’s related to. The preference file or plist contains all the settings for an application. Proceed to the next solution if you still can’t see some columns in the Activity Monitor.ĥ. Drag the divider next to the Processes Name column to the left.

You can also resize columns to view other information you need.

Using two fingers, swipe on the trackpad to the left to scroll through the columns.

If you are using a MacBook, place your cursor anywhere in the main window.

If this is the case, you can follow these tips to navigate the interface: There are instances when maximizing the Activity Monitor is still not enough to display all columns at once. This should maximize the window, allowing more information to be displayed in the Activity Monitor.
