For me QuickTime was not sharing my iphone screen as well. My QuickTime started showing this warning:
can not use Vaibhav's iphone. This app is not authorized to use Vaibhav's iphone quicktime
What I did:
Go to System Preferences > Security & Privacy > Privacy and follow these steps:
There is no misbehavior on the part of the MBP; resetting SMC etc will not address this problem.
When the MBP goes to sleep, the ports are powered off and communication stops as intended. When the computer wakes, RealTek ethernet chips are powered back on, but they do not resume communication. My work gave me an unbranded usb-c to ethernet adapter which ...
You dont say which 2009 iMac you have, but even the Late 2009 27" seems to support only one external display, up to 2560 x 1600. (From things like Everymac.com and MacTracker)
How have you managed to get two external displays running from 1 miniDisplayPort?
I doubt very much whether these machines have sufficient graphics hardware to drive 3 displays - ...
I'm using the monitor USB hub as a connector, could it be an issue?
Yes, that's probably the problem. Based on the speeds you're seeing, I suspect that the USB hub in the monitor is a USB2 device; connecting your drive through that hub is slowing down the connection to USB2 speeds.
Connect the SSD directly to your computer, or use an external USB3 hub.
I own multiple Samsung T3's and T5's. They are incredible.
The cable is important, and unfortunately, it's impossible to tell which cables are intended for which purposes.
Your 2018 MacBook Pro with Mojave (I have a 2017) does NOT need any kind of driver to use the drive. There's an encryption app on the drive that's worth installing so that you can secure ...
The Boot Camp Assistant will not accept Windows 7 because your Mac is a 2015 model. Starting in 2015, Apple eliminated including a legacy BIOS with the Mac firmware. Windows 7 can only BIOS boot and therefore can not be installed on your Mac. It does not matter how you create the flash drive or what method you use in an attempt to install.
According to Apple's specifications on this MacBook Pro all four ports support video:
Charging and Expansion
Four Thunderbolt 3 (USB-C) ports with support for:
Thunderbolt (up to 40 Gbps)
USB 3.1 Gen 2 (up to 10 Gbps)
If two of the ports are not supporting video you could look at the cabling (try another cable, etc.) and ...
No. This will not work. You will need to get a display with its own power supply.
Thunderbolt 1/2 doesn’t support power delivery. Even though Thunderbolt 3 does, connecting an adapter doesn’t magically make power appear.
The (up-to) 9W of power is bus power - you can’t assume that because it’s there, it can be utilized, especially to power a device. ...
i had same heating issue for more than 6 months till i tried this and then everything is just fine.
Increase fan speed to constant 4500 RPM by downloading Mac fan control app
Use a elevated stand while using mac. Lower metal body should have enough air circulation.
Now whether i use external display of dedicated GPU, everything just works fine without ...
Your USB drive is formatted with NTFS file system. By default, macOS can only read a drive formatted with NTFS file system. It does not include drivers to write to NTFS filesystem.
To delete (technically writing, i.e. making changes) the files and folders on NTFS formatted drive, you'll need drivers for NTFS to be installed on your Mac.
If you wish to ...
You cannot allow the Mac to sleep. That is the fix. If you do, just make it standard operating procedure to unplug and re-plug. Been using Mac Pro's for music production for many, many years. This is not a problem, it is just how they work. Same as you can't hibernate a Mac, and you can't wake one up from LAN.
What seems to work on various systems (sometimes)...
You need a Thunderbolt 3 dock - many exist. What you seem to be confused about is that they require a Thunderbolt 3 monitor - they don't. You can buy a simply cable to connect the Thunderbolt 3 port on the dock to the monitor via DisplayPort or mini-DisplayPort.
I'm using the OWC 12-port Thunderbolt 3 dock for attaching dual-monitors to the MacBook Pro ...
the Karabiner download allowed my Sculpt keyboard to work on my El Capitan system. I'm excited as the keyboard suddenly stopped working a few weeks ago for no reason. Happy for this download, will donate coffee $ as suggested
Spinning disk drives fail, and its clicking-then-silence and invisibility to the host computers both indicate that this one has given up the ghost.
Expensive disk-repair software such as DiskWarrior might be able to repair it, or to retrieve the data. Given the clicking noise followed by silence, however, this is very unlikely. I wouldn't expect ...
It is a driver problem. The com.apple.driver.usb.cdc.acm driver actually instantiates an IOSerialBSDClient for the device, as seen in the output from ioreg:
+-o IOUSBHostInterface@1 <class IORegistryEntry:IOService:IOUSBNub:IOUSBInterface, id 0x100007a62, registered, matched, active, busy 0 (208 ms), retain 7>
+-o AppleUSBACMData <class ...
I usually run Linux, but recently got a 2018 MacBook Air and ran into this problem. I have a directory of just over 100 MB in around 200 files that I frequently backup and move between computers using USB-A flash drives. Using USB 3.0 on Linux it transfers in a few seconds, and the drive ejects immediately, in all cases.
When I first did this on my Mac, ...
