May 02, 2019 By default, at startup The Mac opens those applications that were open when it was shut down or restarted. This feature is designed to help users with ease of access and recover or continue with whatever they were doing by quickly reloading the apps that were loaded before the system rebooted or crashed.
I'm a switcher, and I remember looking up how to boot from USB if the bios supports it, and e-mailing somebody to ask why their shareware program didn't support booting from a flash drive.
They said flash drives can't handle quite as many read/write cycles as a hard drive, so it's not recommended for them to go through the hammering a boot sequence gives the drive as it creates and deletes files all over the place. (I have no idea how this translates to the Mac, but it seems to be common-sense that large modern operating systems do A Lot Of Stuff before you see your login, so I'd expect many tiny files to be created and deleted in XP and Tiger).
This suggests that booting from a flash drive all the time (for security or portability reasons) would not be good, because after a matter of weeks or months it might give up the ghost.
It occurs to me that this might mean a flash drive is a really good choice for a minimal system 'rescue disk' in the way people used to keep a boot floppy somewhere. This is because a flash drive seems to be noticeably more robust than floppy, zip, cd-r or hard drive, as far as keeping it lying about and expecting it to work is concerned. I haven't actually tried this myself (I tend to clone the main disc to the firewire disc and hope it all works), but it's an idea.
Terex ta 30 service manual instructions. (Sorry if everyone already knows all this, but it's probably worth pointing out in case anyone's just thinking about it and falls foul of this)
If you try to open a file, but OS X Yosemite can’t find a program to open that file, OS X prompts you with an alert window. For example, if you try to open a very old (1993) file created on a long-defunct Psion Series 3 handheld PDA, the results are shown in the figure.
Click Cancel to abort the attempt to open the file, or click the Choose Application or Search App Store button to select another application to open this file.
If you click the Choose Application button, a dialog appears (conveniently opened to your Applications folder and shown in the following figure). Applications that OS X doesn’t think can be used to open the file are dimmed. For a wider choice of applications, choose All Applications (instead of Recommended Applications) from the Enable pop-up menu.
You can’t open every file with every program. If you try to open an MP3 (audio) file with Microsoft Excel (a spreadsheet), for example, it just won’t work; you get an error message or a screen full of gibberish. Sometimes, you just have to keep trying until you find the right program; at other times, you don’t have a program that can open the file.
Snip and sketch for apple. When in doubt, use a search engine to read about the file extension. You’ll usually find out more than you need to know about what application(s) create files with that extension.
