So I wonder if some aspect of the behaviour in this area has changed. The most powerful system monitoring app for macOS, right in your menubar. I must confess that I don't remember what the settings were under El Capitan but I would hope they hadn't been changed but you can't take that for granted. Download iStat Menus for macOS 10.13 or later and enjoy it on your Mac. I suspect it is the Power Nap setting that did it. That seems to have changed the temperature issue back to how it was before upgrading to High Sierra (ie it was quite cool when I picked it up after leaving it with the lid closed). Looking at the energy saver set up in system preferences, I finally decided to disable the wifi and Power Nap boxes under Power Adaptor as I tend to leave the MBP connected to the power when I am not using it. After being completely boggled on the internet trying to understand sleep/hibernation/standby I gave up on that side of things. I still believe that iStat Menus used sufficient resources to make a noticeable difference to the temperatures but other factors seem to be at play.ĭespite switching off iStat, I still had the MBP warm in the morning after supposedly being "sleeping". I have been active on my MBP even if not on the forum.

I am not inclined to pay for something that I have to completely hamstring to prevent it doing this.

Has anyone else noticed this and if so are there any suggestions as to how it should be used to avoid the issue.
ISTAT MENUS HIGH SIERRA UPDATE
Switching it off gave an immediate cooling down of the laptop and changing the global setting from medium to slow update frequency also gave a noticeable temperature decrease. Further investigation clearly showed it was iStat Menus. At first I thought it was High Sierra as I have only just upgraded but it then occurred to me that it could be iStat Menus. I close the lid and expect it to go to sleep. I was very surprised this morning to find that my MBP was warm as if it had been active overnight. It works OK and I was happy with the summary on the menu bar. If I remember rightly, the first time you run iStat Menus. Looking at reviews iStat Menus seemed quite good. The two processes are called iStatMenusDaemon and iStatMenusFans - you can see them in Activity Monitor and they run as root user. I tried XRG and didn't think too much of it. I looked at Activity monitor which is just too much info.
ISTAT MENUS HIGH SIERRA PRO
Main reason I am trying it is that I want a replacement for the discontinued widget iStat Pro just so that from time to time I can look at aspects of the machines performance. I have just downloaded and installed iStat Menus as a 14 day trial.
