I love my M1, but does anyone else have horrific performance when resuming from wake? It’s like it swaps everything to disk and takes a full minute to come back

I love my M1, but does anyone else have horrific performance when resuming from wake? It’s like it swaps everything to disk and takes a full minute to come back to life.

I tried reinstalling OSX, now it seems fine! ¯\_(ツ)_/¯

Haven’t seen this on my M1 Mac mini; my wake times are faster than my monitors can wake. No performance issues immediately after sleep. Maybe desktop platforms sleep differently than laptops?
- singhkays 6y ago
  Most likely. Same here with my Mini

I haven't noticed poor wake times, but my laptop does kernel panic and reboot a fair amount. Maybe 4 times in the past week. My hunch is that it's Spotify's fault but I haven't dug into the logs.
- Reason077 6y ago
  I've had mine panic and reboot twice, both times happened shortly after disconnecting other Macs that were connected via a Thunderbolt cable (target disk mode).

  How does spotify panic the kernel itself?
- SigmundA 6y ago
  A user-land program cannot be at fault for a kernel panic, that is the kernels fault, always.
  - ridiculous_fish 6y ago
    xnu will panic if it doesn't receive periodic check-ins from userspace. For example if WindowServer hangs, then the kernel may deliberately panic so that the system reboots. See man watchdogd for (a tiny bit) more.
    - saagarjha 6y ago
      True, but a third-party program shouldn’t really be able to do this, at least not easily.
- siquick 6y ago
  I have this problem but only if I've been plugged into a monitor, and then unplugged and gone onto battery. Rebooting after unplugging stops it but its annoying.
Reason077 6y ago
Definitely no issue with waking my M1 8GB MacBook Air. Takes a fraction of a second, every time. In fact, this is specifically something that Apple were bragging about when they launched the M1 Macs!

It’s inappropriate of you to post an offtopic end user technical support question on this post about CPU microarchitecture performance.
- mhh__ 6y ago
  Why? There isn't really anything interesting in this post, beyond that Apple obviously wanted this feature for whatever reason

No, it's perfect, instant wake for me. I have never seen anything like this. I have buggy apps (like Facebook Messenger) locking up, but I guess that's normal, I just uninstall them.
- thefourthchime 6y ago
  Which M1 do you have?
  - xiphias2 6y ago
    16 GB RAM pro 1TB SSD. I guess the only drawback compared to MB Air is that it's a bit heavier.
zitterbewegung 6y ago
Do you have it plugged into a monitor upon wake? How many programs do you have when it is resuming? I noticed this really infrequently.
bombcar 6y ago
I have a non-M1 with Big Sir and it takes more than full minute from sleep to usable. I suspect it’s because I have five monitors and 20 million pixels (actually more as that’s the post-retina resolution).
- monsieurbanana 6y ago
  How does the number of pixels (or even monitors, for that matter), affect that much sleeping time? Rendering a FPS game at 1080p is 2 million pixels per frame. At 60fps, that's rendering 120 million pixels per second. What am I missing?
  - bzzzt 6y ago
    Detecting the monitors, negotiating the correct resolutions, setting scaling factors and window positions after coming out of sleep will take some time. Maybe macOS does monitor setup sequentially? (no idea, just got 1 big external screen that also takes a few seconds to light up - handshake speed seems to vary between monitor brands)
    - bombcar 6y ago
      This is almost certainly it - the screens show all sorts of weird graphical artifacts (some clearly a Retina display in "native" resolution) as it starts and loads. I assume it's having to fire up all the GPU memory, etc.

Instant wake for me. However any time I come across a password field in a website the computer freezes for a painfully long 10 seconds or so while it presumably decrypts my password vault. Sometimes this will happen multiple times per page load if I deselect and reselect the password field.
- Waterluvian 6y ago
  Did you somehow accumulate a bajillion passwords?
  - CameronNemo 6y ago
    Crypto optimizations are no joke. My Pinebook Pro takes several seconds longer than my T430 to decrypt my keepassxc database.
    - coldtea 6y ago
      Why would it need to decrypt a whole database though, and not just the required password? To avoid leaking the key name?
      - CameronNemo 6y ago
        Yes I think it is an all or nothing deal.
        coldtea 6y ago
        Perhaps it could be a two-level thing then, where you first decrypt e.g. the list of keys and then read the one you want and get a "start/end" offset to read/decrypt just the value for that key from another file. So keys and values are still decrypted, but you don't have to decrypt the whole bundle in one step to get the value.
    - akvadrako 6y ago
      Maybe the time is hashing your password. This is designed to take as long as it can while still being reasonable. 1 second on a fast machine isn't unheard of.
kureikain 6y ago
It way faster than my old macbook pro. But one thing is the external monitor won't be open upon resuming. I have to plug/unplug the cable to re-active the external monitor. It seems HDMI handshake was failed somehow
rootusrootus 6y ago
Yes. This is actually a known issue, provided you have an external monitor attached; lots of people complaining about it. The Mac actually wakes up instantly if you lift the screen, but it usually takes 5-10 seconds before it will wake up the external monitor. Worse, for some of us when it does finally wake up the monitor, sometimes it wakes it up with all the wrong colors, and rebooting is the only reliable fix. (and before anyone asks, yes, I tried a different HDMI cable)
- benhurmarcel 6y ago
  Does this happen with the Mac Mini?
- matwood 6y ago
  I think they are still working through some external monitor driver issues. The colors on my LG 4k were initially way off until I did an advanced calibration. Occasionally waking up from sleep it will revert, but opening the Display preference and swapping between the calibrations fixes it. My connection is through usbc. I don't have any performance issues waking up though.
  - rootusrootus 6y ago
    I think there are a couple issues going on with the colors. For some people it is calibration. But what I experience is almost like a color inversion (but it's not a full inversion, it looks like maybe one or two channels got inverted). Makes it difficult to even find the mouse pointer so I can get to the menu and reboot the machine. Then it comes up fine.
    - matwood 6y ago
      Interesting. I did submit a bug to Apple about my issue. Mainly because I never did a calibration with my 2017 mbp and the monitor looked great. With the M1 MBA I had to do the advanced calibration just to make the same monitor usable. Otherwise the colors were completely washed out. It almost seemed like the setting to auto-dim the laptop monitor was also being oddly applied to the external.
TheRealSteel 6y ago
This is anecdotal and I don't have anything to prove it, but I really feel like my old spinning-hard-drive 2010 MacBook Pro woke faster from sleep running Snow Leopard, than the Retina models ever did (or the old ones did after a few software updates). Of course for general tasks it was slower, but I really remember that thing waking up instantly when I raised the lid, every time.
- 2muchcoffeeman 6y ago
  My nostalgia agrees with you, but I think it’s probably wrong. The wake from sleep was what finally convinced me to get my first Mac. Even now they have the best hibernation and wake from sleep.
wil421 6y ago
Nope, my M1 Air is connected to an external monitor most of the day and I don’t have issues.
mindajar 6y ago
Yeah. To me it looks like macOS goes so deep into sleep it disconnects the external display. On wake, the system rediscovers the external and resizes the desktop across both displays. With a bunch of apps/windows open, half your apps simultaneously resizing all their windows can peg all CPU cores for a number of seconds. (It's still way faster than the same set of apps on an Intel Mac laptop, where it could sometimes take on the order of 30 seconds to get to a usable desktop after a long sleep. On Intel Macs it seemed more obvious that the GPU was the bottleneck)
dcow 6y ago
I am using the LG Ultrafine 5K (so it’s a TB monitor) and it takes maybe 1.5s to 5s longer than the built in display (which wakes instantly) to turn on. I do occasionally have an issue where the brightness on the built in display is borked and won’t adjust back to the correct level for anywhere between 30s to a few minutes. And then I don’t know if it’s my monitor or the M1, but sometimes there will be a messed up run of consecutive pixel columns about 1/10th of the screen wide starting about 30% from the left of the display. The entire screen in that region is shifted a few pixels upwards. Sometimes it’s hard to notice it but once you do it can’t be unseen. Replugging the monitor into the M1 resolves the issue.

I love my M1, but does anyone else have horrific performance when resuming from wake? It’s like it swaps everything to disk and takes a full minute to come back to life.
