Dec 14, 2018 Pros and Cons of Mac Os. Following are some of the Pros (Advantages) and Cons (Disadvantages) of Mac OS. Mac OS has a built-in program called BootCamp. It allows you to install windows, Linux or any other operating system in addition to OS X. Setting up the boot camp in OS X is also very easy. And switching between them is. Use the Keyboard Shortcut to Type Check Mark on Mac You can use the keyboard shortcut as “Option+V” or “Alt+V” to insert a tick mark (or check mark) on your Mac computer. It is the most useful and fastest way to type a check mark on Mac to complete your work and move to another task. As a designer I practice proper typography, so the Don't Save on my page would have a proper apostrophe, instead of a 'dumb quote' style which is actually a foot mark. It's sad to hear that the search function of a browser isn't smart enough to figure that out. Browsers should be able to handle that. But it does raise an issue I hadn't thought. In 1984, Apple debuted the operating system that is now known as the 'Classic' Mac OS with its release of the original Macintosh System Software. The system, rebranded 'Mac OS' in 1996, was preinstalled on every Macintosh until 2002 and offered on Macintosh clones for a short time in the 1990s.
With no warning in advance, a flashing folder with a question mark appears when your Mac startup.
What does it mean? A folder with a question mark icon means that your startup disk is not detected or doesn't have a usable Mac operating system.
Commonly, the folder with a question mark happens after you've booted from an external system drive recently, replaced a new HD or SSD, or updated a recent macOS. It could see that both software and hardware errors are the possible causes.
For the worst situation, you can't go past the question folder icon, even with a restart. So, to avoid data loss, recover files from your Mac first. Then, follow the solutions below to get rid of the blinking folder with question mark and boot up your Mac as usual.
Here are the solutions to fix the folder with question mark on Mac in this post:
You can watch this video to learn how to recover data from Mac that won't boot due to the folder with a question mark.
Data recovery is the first thing once your Mac won't boot, which can prevent forever data loss caused by some fixes. As the Mac is unbootable, you can only recover data with data recovery software like iBoysoft Mac data recovery.
Go to run iBoysoft Mac data recovery in macOS Recovery mode to get the lost files back. If you don't want to check the details, watch the above video instead.
You could see the folder with question mark on MacBook Pro, MacBook Air, iMac, or Mac mini. But anyway, you can try to reset NVRAM on your Mac first. If it doesn't work, try the following solutiuons one by one.
If your Mac displays a flashing folder at startup, you can wait for a moment and see if it can boot past the icon.
If fortunately, it continues booting up, congratulations! But just in case, you can reselect a startup disk in Apple menu > System Preferences > Startup disk.
If you Mac can't boot past the flashing question mark, you can manually select the startup drive. You can do this by restarting your Mac while holding down the Option key.
If you boot from an external drive, you can check these factors.
Tips: In the case of some older Mac OS X machines, you can boot from the install DVD or CD that comes along with your Mac in the optical drive.
When the first method won't work, you can boot into macOS Recovery mode. The built-in recovery system of your Mac allows you to reselect the boot volume to fix the flashing folder with a question mark on Mac without CD.
To do this, you can follow these steps.
After you click on the Restart button, your Mac should then start up without the blinking folder with question mark.
Tips: If you can't boot into macOS Recovery Mode from the local recovery system, try Internet Recovery mode by replacing the keys in Step 2 with Option + Command + R (or Shift+ Option + Command + R). Make sure your Mac connected to the Internet at the same time.
If you can't see any startup option in the Startup Disk window, probably, the startup drive is corrupted and that is the cause for the folder with a question mark on your Mac.
Then, you need to check and repair the hard drive with First Aid to boot your Mac from this drive.
The worst situation is that you don't see your built-in startup disk even in the Disk Utility. It indicates that there's a hardware issue. You need to check the connections of your hard drive or contact the Apple authorized service for Mac repair.
Some other times, the startup drive is showing up in Disk Utility. However, Disk Utility finds issues with your startup disk that it can't repair. In this case, you need to move forward to the next part.
After trying First Aid, you still see a folder with question mark during Mac rebooting, which means your startup disk has serious corruption. You need to reformat it and assign a new file system.
However, reformatting will wipe your files off the hard drive. If you don't have a backup of your Mac, you would lose important files after reformatting.
However, you can follow this safe guide to reformat the startup disk without data loss:
Now, you'll have a fresh new Mac hard drive but it contains no Mac operating system. To boot your Mac up without the flashing folder with question mark, continue with reinstalling macOS in macOS Recovery mode.
How to Reinstall macOS to start up the Mac?
Here is a guide to reinstall macOS to start up your MacMacBook Pro, Mac mini, MacBook Air, and iMac. Read more >>
You internal Mac hard dirve is working on the basis of HDD cable transmitting the electronic signals between the logic board and the hard disk drive. Therefore, once it's loose, damaged, broken, or deformed, you might get the Mac folder with quesiton mark at startup.
Here is how can you check the connector of the startup HDD. Note that ask someone prefessional to help you do this job is necessary.
The SATA hard drive is connected to the logic board in your Mac in the way of bending 90 degrees twice. This particularly can be seen in 13' MacBook Pro 2012 model (on the edge of the super drive).
So, it's likely that the copper wire inside the flexible plastic cable is broken or damaged at the bent section.
Then you'll need to replace it with a good HDD cable.
If your Mac mini, MacBook Air, or MacBook Air shows folder with a question mark, you can check the SATA connection like this.
This works well if your Mac doesn't recognize the internal hard drive for booting up. But if it doesn't help, either the hard drive or the SATA connection is damaged. You'll ask for a repair or replacement service from Apple.
If you see the Mac folder with flashing question mark after a recent macOS update, it may be a result of incompatible firmware that should be automatically upgraded by the installer.
Possibly, the firmware fails to complete the update during the whole system update. Then, the new system can't be recognized by the old firmware, causing boot issues.
To re-update the firmware, you can manually erase the disk and reinstall the macOS with stable network connection and enough free disk space.
Inside MacBook Pro in 2016 and 2017 with Tochbar, a critical bridge connector called lifeboat is used to connect the SSD circuit to the CPU so the CPU can read and write data to the SSD chips.
However, if you have send it for repair and forget to put it on, or if the lifeboat connector cap is not functional, you will get the flashing folder when turning on Mac.
Here are some basic checks you can perform to make it work again (Do these checks with someone professional):
Sometimes, Mac can't find the startup drive just because the drive itself is in trouble.
Your removable SSD drives on the Mac logical board is connected using SSD sockets. Once these components are corroded, damaged, or dusty, you'll receive the 'Mac folder with question mark' error on Mac booting up.
So, think if you have spilt any liquid on your Macbook Air or Pro. If you see the SSD socket is corroded, you can cut off the corrosion and map the pins with 99% alcohol. If it doesn't help, you need to replace the socket.
For most Apple iMac, pre-2013 MacBook and MacBook pro that use mechanical hard drives, the Mac flashing folder with question mark appear when there is a mechanical disk failure, and you might hear beeping or clicking noise. Or if you can't feel the vibration of the hard drive spin motor, the hard drive is dead.
Go ahead to replace or upgrade it with SSD, and reinstall Mac operating system.
Conclusion
Most of the time, errors like the circle with line through it and the folder with a question mark on the Mac/MacBook screen means a system software issue. You can simply fix this by reinstalling macOS (Remember to recover data first).
If macOS reinstallation can't fix the Mac flashing folder issue, it could also result from the hardware issues. In this case, you'd better send your Mac to a trusted repair store.
