Memory pressure has always been green, yet Menu Meters > shows 1118 pageouts. 1118 is in the normal range. 50,000 within a day is pretty high. Note that the counter starts at boot, so the longer your machine runs, the higher the number will go. > It also says there's no swap file. I'm not sure why you are so fixated on whether there is a swap file - it's inconsequential. > It looks buggy to me. If Raging Menace writes an El Capitan version, > maybe that will fix it. What looks buggy? The Menu Meters swap file widget? That wouldn't surprise me. I used to use it and it was rather buggy compared with other alternatives. > I haven't found any pageout information in Activity Monitor. I wonder > why it's not listed. Memory pressure is more useful as an indicator of low memory. If you want to see pageouts, you can run this command in a terminal window: # memory_pressure The system has 2147483648 (524288 pages with a page size of 4096).

No idea. I haven't used Menu Meter in a few years. -- E-mail sent to this address may be devoured by my ravenous SPAM filter. I often ignore posts from Google. Use a real news client instead. JR
