It seems resetting the SMC that handles the current during sleep/wake function of your macbook pro retina might work.
Try force touch click on it – then it becomes alive again without need to restart.
“The Force Touch trackpad lets you Force click by pressing on the trackpad and then applying more pressure.”
Thanks for your advise. It worked. Had a chat with apple support and solved it.
“…there’s a component on the computer known as the SMC which controls both the sleep/wake function,And the distribution of the battery’s power,Which would include the current shared with the trackpad and its click button,…..try resetting the SMC….To do this, we’ll need to power down the Mac….While the computer is OFF, we’ll hold down shift, control, option and the computer’s power button, all together for ten seconds……..IF you do this right, the computer SHOULD NOT turn on………And it should reset the SMC, which could fix the situation that you’ve been experiencing about the distribution of your computer’s current as it relates to the sleep/wake function and your trackpad click…..”
Step 1: Connect Your External Hard Drive To Your Mac
First, connect the hard drive to your Mac and make sure it shows up in the Finder’s sidebar. Copy something to the hard drive from the desktop just to make sure it works. If it doesn’t then it might not be formatted to use with a Mac (most external hard drives aren’t). If that’s the case, you’ll need to first reformat the hard drive to FAT format.
Step 2: Connect Your iOS Device To Your Mac
The first thing you need to do is connect your iPhone or iPad to your Mac using the USB to Lightning connector you got with your device.
Step 3: Launch Image Capture
Image Capture on Mac is one of the most underrated utilities. To launch it, search for “Image Capture” using Spotlight search (using Cmd + Space shortcut).
After you launch it, find your iOS device in the left sidebar and click on it.
You’ll now see a list of all the photos on your iPhone or iPad right there.
You can either use the keyboard shortcut Cmd + A to select all or just individually check mark all the images you want to import.
Step 4: Select Destination
By default, photos will be imported in the Pictures folder. Click the drop-down, and select “Other”.
Now select the folder in the external hard drive as a source.
Step 5: Click Import
Click the “Import” button and wait until the transfer is done. If the external hard drive is USB 2.0 spec, and you have a lot of photos, this could take more than just a couple of minutes.
Of course there are several prerequisites, but simply spend some time fixing them, and you’re going to thank me for the amount of time you have saved.
The problem with all the guides around is that they are mostly written by hard-core or self-taught developers – so only they would understand what they teach. And most of these guides are hard to follow and get right. That’s what this site is for, building advanced guides that are simple to follow – for the pros and newbies alike.
