The way MacOS Install generally proceeds is this:
The way MacOS Install generally proceeds is this:
a chunk of new software (actually a minimal system of the Incoming software) is ADDED to your boot drive. This does not replace you current system.
The start Disk is set to the newly copied minimal system
A restart occurs, booting to the new System.
If the Install gets in trouble at this point, your old system is still intact, it just needs to be re-specifed.
All you need to do is get the startup disk set back to the old system.
You can boot to recovery (Command-R), then quit recovery, and Startup Disk will be activated as you quit, and you can re-specify your Startup Disk.
You can Alt/Option Boot and select your regular Startup disk and tell it to proceed, Once Mac OS is active, be sure to use:
System preferences > Startup Disk ...
... to set the startup disk normally again.
if you would like help on making the Install work, please post the exact model MacBook Pro, including year and screen size, or the MacBook Pro 17,2 designation.

What version of Photos are you using? Because I am using Photos 3.0 (the one in High Sierra) and (1) the button with the lines was replaced with one that just says "Edit" and (2) that button only shows up after either double clicking on an image to enlarge it or highlighting an image and then hitting Enter to enlarge it.
I just update my MacBook Pro to Mac OS High Sierra and I later found that QuickTime cannot open AVCHD file. What shall I do?
The basic problem here appears to be error trapping associated with the "pre-scan" of the file before opening the data in the QTX player app. (I.e., under High Sierra, it now appears that mono, 2-channel mono or stereo AC3 data in certain file containers is "error trapped" during a pre-loading scan of the file data.) Since AVCHD is basically AVC video muxed with stereo AC3 audio, the operating system refuses to allow the data be loaded to the QTX media player. (The same thing happens to my H.265 videos containing a mono, 2-channel mono or stereo audio track.)
You have a number of options here. You can complain to Apple in Feedback or Bug Reports and hope the issue is fixed sometime in the reasonably near future. Another, more immediate workaround, would be to convert the MTS files to MOV, MP4 or M4V files containing user targeted audio and video compression formats or, if you have the appropriate software available, you can copy the AVC video "as is" to a new file container while simultaneously transcoding the AC3 audio to AAC. E.g., an app like Subler (or Smart Converter Pro) can copy the original MTS AVC video (High@L4) to an M4V or MP4 (or MOV) file container while transcoding the AC3 48.0 KHz @ 256 Kbps audio to AAC audio. Be advised, however, that different apps may default to different AAC transcode settings. (I normally use one of the latter options to preserver the original video quality.)

Thanks for the advice dv, but you don't understand the issue. I'm well aware of how to view and download email attachments. Been sending and receiving them for many, many years. There were no attachments in the emails at all. So, no attachment icons either. However, it turned out the senders forgot to include them . So, it wasn't an Apple Mail issue after all. It was user error on the senders' side.

Last time I upgraded my OS, things went very well. I figured it wouldn’t be the same case.
Also, I must have not been paying attention in my “Trusting Apple With The Product They Are Releasing & The Do’s and Don’ts When Upgrading Your OS 101” class back in grade school. The way your reply sounded made it almost seem like everyone in the world has this super special spidey-sense regarding backing up an OS. Apple releases something claiming to upgrade and enhance my laptop, sends me a notification to download it, and apparently that’s enough reason for you to talk down to me.
“Hmm yep, told that guy. Problem solved.”

Don't use capitals and don't use colours please.
Wait with upgrading to HighSierra until you are sure that your issues are solved definitely.
To avoid a lot of questions from us, download and run a diagnostic app, etrecheck, run iz and post the list here:

The question mark folder means your Mac cannot find a valid system to startup from. It sounds like your hard disk is failing/failed. If you have another disk with a system on it try starting from that. You'll probably need to replace the hard disk. Hopefully you have a good backup. If not, after installing the new drive, put the hard disk in an enclosure and you may be able to recover your data that way.

I have the exact iMac 2013 (21.5, 2.7 i5, with Irish Graphic). I am running 10.13.1 and did not have any issue. I did an "upgrade" from 10.12.6 to 10.13 then 10.13.1 -- it seemed to be quite smooth during the process. However, 21.5 inch (after 2012) iMacs (without Fusion drive or SSD) often suffer speed problem from the notorious 5400 rpm HDD.
Since I downloaded MACos High Sierra my computers colours and screen is corrupted and I cant view photots properly either I get a black picture

Select your internal drive. OS X Base System refers to an installer. You cannot install on it.
The above link will not work under Sierra in which case you should try using gfxCardStatus.app.zip.
