You have a hardware issue.
There are two errors:
ERROR - -12100 [IOConnect error reading from PCI address space] -- TEST FAILED
ERROR - -12105 [PCI driver IOService open error] -- TEST FAILED
Both have to do with I/O (input/output) operations on the PCI bus.
The first, related to the AirPort card says that it can't read from the "PCI address space." ...
Using Karabiner event, it seems like keystrokes on Fn keys are not detected by the Mac. Can I fix it?
You can’t remap the Fn key as it’s an internal keyboard modifier and not sent to the OS
See this answer from a similar question for full details.
Basically, if a scan code isn’t sent by the keyboard to be received by the OS (and the Fn code isn’t), ...
I'm the author of the Apple SSD article that klanomath linked to in their comment and I wanted to clarify some things that seem to have been misinterpreted.
First of all, the Mid 2013 release of the MacBook Air 11" absolutely can use the faster PCIe 3.0 x4 drives from the 2015-2017 MacBook Air 13", which I refer to in the article as the Gen. 4A SSDs.
Short answer: yes, almost any changes you make on the disk have a possibility of causing further damage. Back up anything important (making minimal changes as you do so), then try to diagnose and fix it.
Long answer: there are several different levels where you could have data corruption/damage:
There might be a hardware problem -- failing drive, bad cable,...
I recently had this problem, or I thought I did, in Keynote. Keynote would open new files in tabs, not a new window. It looked like my original file was gone but it was still there is a different tab. Look under the toolbar in excel and see if there is another tab open.
This is an olde post I know but I have just had the a similar problem, and via trawl around the web came here and tried the suggestions above. Sadly they didn't work. However I also came across what did work for me.
Simply unplug the power adapter from the mains for a few seconds; then plug and switch on. èt voila the charging process now starts OK - the ...
The developer of "Thunderbolt3Unblocker" lists this as a known issue and recommends a firmware update on the TB16 which apparently helped some users.
video output does not work. Unfortunately, this is out of scope for this project.
We can only speculate wether the issue is caused by the swollen battery.
A swollen battery can be a hazard and should be swapped either way.
Apple offers extra warranty for batteries that are swollen (2-3 years from purchase depending on the device). An AASP (Apple Authorized Service Provider) should be able to swap the Top Case (which will include ...
That photo says the kext (driver) for the Atheros airport card is what's causing the kernel panic.
There's a very simple way to disable this kernel extension, although it's terribly hacky: go into /System/Library/Extensions/, and rename IO80211Family.kext to IO80211Family.kext.bak.
Afterwards, go into the Terminal and run sudo kextcache -i / to rebuild the ...
For wired headphones you have a lot of options. Bluetooth literally is a digital signal, so you have no options other than better receiver to power your headphones. Since you can’t change out Mac amplifier to increase the current or voltage you have two choices For analog:
Choose lower impedance headphones or more efficient headphones (Sealed or noise ...
While the answer by @user3439894 indicates that the mac firmware should set VMX on during boot it doesn't in either my 2013 or 2014 MBP. This means that Hyper-V (in bootcamp) does not work without a fix.
To tell if vmx is actually enabled you need to check the 0x3a CPU register - see Activating the Intel VT Virtualization Feature. This can only be done ...
How are you so sure that there is no air being moved around?
Further, when does the throttling apply - right at the start or after some time? Because at some point under high load, you will experience some throttling on basically any laptop.
The only thing - depends on how familiar you are with such things - I can think of, is taking the back cover off and ...
I am experiencing something similar, and it is actually the Apple Magic Mouse 2 that creates all the interferences with other Bluetooth devices.
I guess something got very wrong in my mouse. If it is on, no Bluetooth device works properly
Firstly, try disabling WiFi before you sleep or power it off in case that is preventing sleep or waking it excessively.
I would get Apple service to run a battery diagnostic. This is the sort of thing they can very rapidly diagnose and easily measure if they have it in for service.
You should have months of stability if you charge your battery to 50% ...
I have tried without success. I believe Mojave doesn't have the necessary drivers.
You can indeed downgrade if you have an older MAC. First, you will need to revert the File System changes though. Catalina creates a volume with 2 disks Macintosh HD and Macintosh HD data.
Start recovery mode (Command+R), open Disk Utility, select the disk and then Delete ...
I ended up not migrating the whole machine. Since Catalina supports only 64-bit apps, it makes more sense to re-install one by one. Since most of my files (data) are synced online, no need to move them over either: I can find them back using a cloud storage solution (iCloud, Dropbox, OneDrive or pCloud).
The most important thing I needed to migrate over ...
Not sure if this would solve the issue but you could try and pass by the Apple store or certified repair center and see if they could help you recalibrate the trackpad.
Service centers have tools to calibrate trackpads. I've been an Apple Certified Mac Technician for 6 years and we do this every time a machine has been opened.
There is a lot of different things that can be the reason but I suggest you simply
Open System Preferences and make sure Show Wifi status in menu bar
Then while pressing the option key, click on the wifi icon in the menu bar.
Select Open wireless diagnostics.
Follow the on screen instructions and you should get your answer there without
Just to make sure... Is visibility for 5G Wi-Fi network turned on? I.e., network is visible in the list of available networks, when you want to connect from any other device?
Also, try this:
Turn WPA2 only in the router settings..
Remove saved 5G Wi-Fi network on MBP and register again.
Just in case, make sure your MacBook supports 5G connectivity by:
I’m missing your use case. There’s no need for male to male since no lightning device charges another except for the one year a pencil didn’t charge wirelessly. Apple made the female to female adapter to allow that.
Surely they would make a male to male adapter if there was any use case for that intended.
Same with a hub, lightning is designed as a very ...
Without the firmware password you will need to take your machine to an Apple Store or official Service Provider, along with proof of ownership.
Ref: Apple KB: How to set a firmware password on your Mac
The old 'remove the RAM' or 'reset NVRAM' tricks etc only work with older PowerPC Macs, not Intel.
You have the exact opposite symptom, but exact same problem as described in the question Force sound's output on speakers.
Basically, the audio jack is broken. There’s a physical switch that’s stuck in “speaker mode” and it cannot be switched via software.
In a nutshell, it seems you need an overview of how to do this. All macos versions from the App Store have a built in utility section where you can open terminal and run createosinstaller script to make a bootable USB installer from the downloaded installer app. Most do not require an AppleID in the App Store, but you might have to set that up as well. You’...
Check out Apples help as indicated below, but unofficially it looks like the Answer is two total external displays can be attached regardless of resolution or which side they are attached. Apple does not really mention QHD but its close enough to 4K, that you probably can't double it with the existing hardware.
Check your requirements
Check the ...
I used to work at an Apple certified repair center and would definitely suspect the SSD. Things you could check:
Reseat the sata connector on the logic board side
Try a different sata cable
Try a different ssd
Put the ssd in a diffent machine and see what happens
Unfortunately not everyone has multiple ssd, parts and machines to test with. Can you try and ...
The problem is the macOS continues to check for updates (including email, software, news, etc.) while your MacBook Pro is asleep (this feature is called "Power Nap"). This means it's very quick to get up and running when you open your MacBook, but it also means your battery goes down while it's asleep.
The problem some people have is that even with "Power ...
Your current MacBook Air has an L1 cache of 128 kB. So your guess of 10^5 bytes is not far off!
The latest MacBook Air has the same amount of L1 cache, so in that respect it is the same. However, other parts of the CPU are vastly different.
Note that your might see that some of these CPUs are listed as having "Smart Cache", which essentially means that ...
This is very much possible using ScreenFlow: https://www.telestream.net/screenflow/overview.htm
It's a paid app but very high quality and straight forward to use. Whenever you create a new recording it gives you options of recording audio/video from all available inputs, including the screen, camera, microphone, and internal computer audio.
There's nothing about i7's in particular the determine that they should always lead to more fan noise than an i5. In many cases, i5's and i7's have similar thermal design power points.
Note that you're comparing an 2013 MacBook Pro with an i5 with a 2015 MacBook Pro with an i7. They're different in many ways. Therefore you cannot really say anything ...
I think it's impossible (pre-APFS) to delete the first partition. You can expand a partition 'upwards' into free space, but you can't move down a later partition.
If you think that stuff on the boot volume could be deleted until there's sufficient free space, then that might be enough to get you up and running for the time being.
Easiest would be to boot ...
I don't believe @oa-'s answer is correct.
I am running Catalina (10.15.2) and was able to get a slightly modified method to what is mentioned in the link from OP working just fine.
First, you need to specify -int before the number of seconds parameter:
defaults write com.apple.notificationcenterui bannerTime -int 2
Otherwise, it's written as a string ...
Apple have released a Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter.
I have one of these. It works well, still providing access to the extra ports on the back of the Thunderbolt Display.
2 issues I have with the adapter: (1) it is quite long and slightly unpretty ...
Copy your .heic file into /Library/Desktop Pictures. Then, you'll need to somehow get the list of pictures to repopulate. This seems to sometimes happen to me when unplugging displays, or just after waiting long enough, or, most reliably, after a restart. Then your new desktop should appear in the list of Dynamic Desktops under System Preferences:Desktop &...
See https://everymac.com/systems/apple/macbook_pro/macbook-pro-retina-display-faq/macbook-pro-retina-display-13-how-to-upgrade-ssd-storage.html for a lot of details about how to upgrade the internal disk of a MacBook Pro, including information about compatible drive models and instruction on how to actually replace the drive.
It probably goes without ...
I see two possible problems here:
First possibility is that your MAC address after reboot is somehow invalid (i.e. for example set to all zeros). That could make your DHCP server (probably in your home router) reject your request for an IP address).
Check if that is the case by running the following command in the Terminal:
Note the line ...
To my experience, it is a question of Secure Tokens, if it doesn't accept the admin even though it has the shipped (old) macOS installed from the recovery partition.
Even though you have created an admin account, you need it to have a Secure Token and update the preboot, for the recovery partition to accept it.
I did the following (when logged in as the ...
spindump is used by various system components to create reports when an unresponsive application is force quit. Reports are stored at:
So what you could do is to have a look at that directory to see which application required a lot of forced quits (aka crashes). Please raise a new question if you need help in reading the ...
No. These SSDs are not compatible.
The 2013-2015 MacBook Air 11" uses a proprietary PCIe 2.0 x2 SSD.
The 2015-2017 MacBook Air 13" uses a proprietary PCIe 2.0 x4 SSD.
The 2015 through 2017 MacBook Air laptops use the exact same interface, so, those are compatible. Also remember that you're comparing the 11" to the 13" model and those are different with ...
It is possible that this last one is causing the black screen at boot? - I don't know yet. With verbose mode enable at some point it appears a message relating the reboot to a kernel panic.
Should I move it to another folder? - I've moved it. Don't know if it effects the boot sequence, but the behavior got regular.
Boot to a black screen, press power ...
This is not a standalone answer, but since comments can't contain pictures, I added a new answer showing the picture requested in a comment above.
Here's a picture that shows a magnet in action, fooling the lid sensor into believing the lid is closed while the lid is open. The purple thing is a magnet used to attach a paper to a whiteboard. The paperclip ...
in the meantime problem is solved. I don't know what solved it. But I let it continue the 2nd time. After 30 min it ended up with an installation error, mentioning something about memory access problems. I restarted the whole thing again. Everything was the same, but this time it worked :). Now the next part, where it all started. Install windows 7 on ...
Same behavior here on my Macbook Air 2013 with High Sierra (but had already the same problem for years or as long as I can remember). When I hit space with one or more images selected in Finder to do a quick view, the first photo displayed has nice bright colors. But as soon as I zoom in or browse back and forth between images, they turn dull, washed-out, ...
If you don't want to use extra keyboard and mouse drivers you need at least version 5.3 of the Linux kernel (the current stable version is 5.4.8). As mentioned in your link to State of Linux on the MacBook Pro 2016 & 2017
Keyboard & Touchpad
Works out of the box with Linux 5.3 and above.
For earlier Linux versions you can get the ...
