2017 Macbook Air suddenly wouldn’t turn on/wake up

My Macbook Air drained out of power and now i plugged it in and it wouldn’t startup again. I tried resetting the smc, resetting the ram.

One peculiar thing i noticed is that the magsafe power cable is showing red as it is charging. But when i press the power button, without holding or with holding. It turns to green and then changes back to red.

The mac is just 1 year 3 months old. This shouldn’t be happening.

Outlook 2016 suddenly asking for password but won’t accept it

I have a windows 10 workstation that suddenly started asking for my outlook password. It is an O365 on a windows network. I have tried to reinstalled, remove, delete credentials, etc to no success. It isn’t a password issue. I can access outlook with the same account on another device not on the network or at Office online without issue. Any ideas? My next thought was to remove the computer from the domain or to delete the device from Azure AD. I am open to any help.

Thanks in advance.

I’ve suddenly lost all my Gmail notes on my iMac Pro

I’ve suddenly lost all my Gmail notes on my iMac Pro. By lost, I mean I open the Apple notes app and see no items.

  • I lost them on my iPhone last week and was unable to find a good documented process to follow to fix – so the notes do not sync with my iPhone today.
  • I could still see them on my iMac Pro.

I decided to go and forward them to iCloud Note so I would never lose them again, [Here is the process I used to “forward them – please describe what you did or better – link to an online article explaining what process you followed]

Usually, they are in my email files (mail.app? A screenshot might help us help you here) and also show in the notes app.

How do I retrieve my critical Gmail notes?

Why has LightDM suddenly started crashing when using Nvidia graphics?

I have an ongoing problem where if I switch to the Nvidia GPU after a suspend/resume with the Intel GPU, I get constant dmesg spam like this:

[63280.031049] nvidia-nvlink: Nvlink Core is being initialized, major device number 240 [63280.031360] nvidia 0000:01:00.0: vgaarb: changed VGA decodes: olddecodes=none,decodes=none:owns=none [63280.031378] NVRM: The NVIDIA GPU 0000:01:00.0                NVRM: (PCI ID: 10de:1c8d) installed in this system has                NVRM: fallen off the bus and is not responding to commands. [63280.031419] nvidia: probe of 0000:01:00.0 failed with error -1 [63280.031430] NVRM: The NVIDIA probe routine failed for 1 device(s). [63280.031430] NVRM: None of the NVIDIA graphics adapters were initialized! [63280.031492] nvidia-nvlink: Unregistered the Nvlink Core, major device number 240 

After a reboot, usually everything would work fine, but not any more: if I reboot with the Nvidia GPU selected, LightDM exits immediately; eventually systemd gives up starting it and I’m stuck at a black screen with a blinking cursor (though SysRq+R then Alt+F1 gets a TTY I can log in at).

Switching to the Intel GPU (prime-select intel) in another TTY and then restarting LightDM (systemctl start lightdm) works absolutely fine, so I have some ability to debug the system, but no way to use the Nvidia GPU.

Immediately before this started happening (using the Intel GPU), I installed the packages clinfo, ocl-icd-dev, ocl-icd-opencl-dev, opencl-headers and beignet-opencl-icd, and then purged beignet-opencl-icd. I then prime-selected the Nvidia GPU and rebooted, and then ran into this problem.

When the system boots in Nvidia mode, the Nvidia drivers appear to be loaded – they appear in lsmod, and dmesg reports that the kernel is tainted. LightDM appears to exit after X dies with SIGABRT, per /var/log/lightdm/lightdm.log:

[+0.00s] DEBUG: Launching process 1435: /usr/bin/X -core :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch [+0.00s] DEBUG: XServer 0: Waiting for ready signal from X server :0 [+0.00s] DEBUG: Acquired bus name org.freedesktop.DisplayManager [+0.00s] DEBUG: Registering seat with bus path /org/freedesktop/DisplayManager/Seat0 [+0.00s] DEBUG: Loading users from org.freedesktop.Accounts [+0.00s] DEBUG: User /org/freedesktop/Accounts/User1000 added [+0.18s] DEBUG: Process 1435 terminated with signal 6 

X seems to start but then immediately exit a few times (/var/log/lightdm/x-0.log):

(==) Using system config directory "/usr/share/X11/xorg.conf.d" xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) (II) Server terminated successfully (0). Closing log file. 

but then starts properly crashing:

(==) Using system config directory "/usr/share/X11/xorg.conf.d" xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) (EE)  Fatal server error: (EE) no screens found(EE)  (EE)  Please consult the The X.Org Foundation support           at http://wiki.x.org  for help.  (EE) Please also check the log file at "/var/log/Xorg.0.log" for additional information. (EE)  (EE) Server terminated with error (1). Closing log file. 

I’m running Ubuntu 18.04; my machine’s CPU is an Intel i7-8750H, and the discrete GPU is an Nvidia GTX 1050 (which is not supported by nouveau, so please don’t suggest using open-source drivers). Kernel version is 4.15.0-43-generic, and the installed Nvidia drivers are at version 390.77.

I’m happy to provide additional debugging information as necessary.

K9 suddenly wants to encrypt all mail, and won’t send any

Obviously, I have inadvertently changed some setting, but can’t figure out what.

I use K9 with 6 accounts, none of which have previously used encryption (I would prefer to – my correspondents wouldn’t). Suddenly all of them, when I try to compose an email have a red padlock at the top right and a tooltip appears at the bottom saying

“Cannot connect to crypto provider; check your settings or click crypto icon to retry”.

On the individual account settings, and also on global settings, the Cryptography tab shows :

  • OpenPGP App – None
  • Show unencrypted signatures – unchecked
  • Autocryptography Mutual Mode – unchecked.

I cannot find any other cryptography options and do not remember changing any. What might have caused it (a very slim chance, but I can think of nothing else) is that it first occurred when I used FireFox Focus, which is privacy oriented and always runs in private mode, to share a link to a web page. Perhaps that changed some setting?

Well, it doesn’t really matter how it happened, but now I cannot send any mail without this error message.

How can I disable cryptography in K9?
