Why I unexpectedly have the terminal icon in my dock?

Hello!

I don't think that I have consulted my terminal, and yet, I just noticed in my dock.  When I clicked it, I received this message:

margretcollins - bash - 80 x 24

Last login: Tuesday March 15 10:33:42 on ttys000

Margrets-MacBook-Air: ~ margretcollins$

Thus, the name is mine and I think that my mac is called 'margrets-macbook-air '.  Don't know how to check this.

I tried to view the contents of a CD of medical imaging that is formatted in CDSView (which is only for PCs).  When you are prompted to search for an application to open, I research and went to the app store where I read on an application, but does not download it.

I know that ttys000 refers to the first selected Terminal. However, I don't know exactly what a terminal is or how it relates to my mac.

Other that that, I did not something extraordinary: just read email, some articles online, looked at my calendar, looked at Fitbit data of sleep and that's it.

Nobody knows what causes the terminal pop icon in your dock another intentionally research on the terminal and access? Anyone know if there is an indication of any malicious activity, i.e. is someone pretending to be me, poking around in my mac?

Thank you!

Unix-based operating system on your Mac (OS X).  The Terminal application, which resides in your Applications > Utilities folder, is used to enter Unix commands directly.

A way to see the name of your computer is through system preferences > sharing.  The name you specify appears valid.

It is therefore likely that your attempt to view the contents of this CD opened Terminal.  I don't worry about this.

  • Why XP machine removes the program icons to game out a journal of my son in office if I remove it from my office after having suddenly appeared?

    It is an odd. I used XP for more than a decade. Of course, I know it's old. I have an ACER of 10 latest Windows that I use. I am the admin. on the XP computer. But for some reason, when it installs all new video games and it allows to put an icon on his desktop, he puts one on my desktop also. Not only which is strange, but if I can see and delete it, it removes from his office, and I think he even took his fully front access so he had to start over and reload the game. So, he loses any accumulation of points which is of course essential to the advancement and is tedious to do it again.

    I think that I could save some time by going in the trash and restoring them on my desk and suddenly they were on her too.

    He could have at one time logged in as me (Admin) and got an Admin too. But it remains in my journal in never just and plays games or even to install them.

    If it has mystified me. WTH?

    Your 'office' is derived from the contents of two folders.  In Windows XP, those are C:\Documents and Settings\All Users\Bureau and C:\Documents and Settings\ is the name of the currently logged in user.

    Many programs put their shortcuts in startup in C:\Documents and Settings\All Users\Bureau.  In this way, the shortcut is visible to any user, whenever the user connects.  On the other hand, if the shortcut is deleted by any user, it is removed for all users.

    To solve your problem, sign in with your "computer administrator" account, open Windows Explorer and navigate to C:\Documents and Settings\All Users\Bureau.  Find the shortcut (s) in question and move them in C:\Documents and Settings\<>

  • I don't have the desktop icons, task bar or the start menu. All I have is my wallpaper.

    I think I'm done inadvertently the Explorer.exe process when trying to figure out which bogged down my laptop. I have now no start menu, no desktop icons, no task bar... nothing! The paper just painted. When I right click on the wallpaper I get nothing. I have no idea how to get that back. If I had not left my email up, I wouldn't even be able to access the internet!

    Hello.

    You should be able to press Ctrl + SHIFT + ESC to open the Task Manager.
    From there, click on file > new task (run...), then type "explorer.exe" in the dialog box and click on enter.
    Of course, should explore back upward during restart as well.
