"iCal" can't be modified or deleted because it's required by Mac OS X.

I have tried to restore a previous version of iCal from a time capsule back up, but keep getting the error message
“iCal” can’t be modified or deleted because it’s required by Mac OS X. can anyone help?

Ah - you mean your calendars rather than the iCal application. It's no good trying to restore the application: the iCal calendars are held in (user)/Library/Calendars and you would need to restore the earlier version of that from a backup such as Time Machine.
Even if you able to do this, syncing will just remove the deleted items again. Are you syncing with MobileMe? - please see this page:

Click the Apple menu at the left end of your menubar. Select "About this Mac." You will get a window like this:

HT201628 I tried following the steps in this article. When I attempt to delete iTunes, it says "iTunes" can't be modified or deleted because it's required by Mac OS X. What other steps could I take to get my MacBook Air to recognize my iphone again?

I tried following the steps in this article. When I attempt to delete iTunes, it says “iTunes” can’t be modified or deleted because it’s required by Mac OS X. What other steps could I take to get my MacBook Air to recognize my iphone again? Neither iTunes nor iPhoto recognize my phone any longer.

iTunes can't be deleted because it comes with OS X. In order to delete it, open Terminal and copy:
sudo rm /Applications/iTunes.app
This will remove iTunes, so then you can reinstall iTunes

TM error: can't be modified or deleted because it's required by Mac OS X.

I found the TM didn't restore 2 folders which are most important after I reinstall my OS.
namely, the "applications" and "user" folders.
which appeared the "xxxx" can’t be modified or deleted because it’s required by Mac OS X error message.
therefore, all my past applications are not restored after the reinstallation.
what happened?

it's strange that those things were not transferred in the first place. they should have. this might indicated that there is a problem with your backup. when you are attempting to restore applications by hand don't restore the whole Applications folder. the message you got indicates that this is what you were doing. restore only the apps themselves. also, you can do it ONLY with applications that were installed by drag and drop into the Applications folder. if an application was installed using an installer you can not restore it this way and should reinstall it from scratch.
what exactly in the user folder are you trying to restore? some folders in your home directory are protected by deny delete ACLs and can not be restored like this. this includes your whole home directory, and all the default folders on it's top level. but you can restore files and folders inside those and any files and folders you created yourself.

"Safari" can't be modified or deleted because it's required by Mac OS X.

Trying to delete Safari I get the message “Safari” can’t be modified or deleted because it’s required by Mac OS X.
Trying to delete through Utilities/Terminal using "sudo rm -rf Safari.app" didn't work as Terminal
froze at the typing in of Password stage.

But I want to use Safari; I have Safari 7.0.4 in Applications which is incompatible with my 10.8.5 system.
Carolyn Samit recommended trashing one copy of Safari so I could use the other (6.0.3) which I have (from a back-up)
If I try to use the 6.0.3 on my desktop it says Safari can't open because of a problem.

"[item name]" can't be modified or deleted because it's required by OS X.

OK, so I purchase ID3 Editor.
• Download a .dmg file.
• Open disk image:
• Instructions tell me to copy software to Applications folder. Which I do.
• Want to rename the Extras folder so that it reads "ID3 Extras", and shows up next to the App it refers to when in list view (have done this forever in Mac OS)
• OS will not allow me to rename folder. If I highlight it and hit "return", nothing happens.
• OK, I create a new folder, name it what I want, move the contents of "Extra" to the folder. Done. Now all I have to do is to delete the unwanted, empty, folder, right?
• Wrong, when I try to delete it, by any method, I get the message:
“Extras” can’t be modified or deleted because it’s required by OS X.
I've just installed this item. It is NOT required by OS X for anthing. I should be able to modify my Applications folder at will.
Will someone, for the love of God, tell me how I might be able to delete this unwanted, unneeded folder from my Applications folder?

You can't. Either turn it on or off. Why do you need to use VO's activation keys? Why can't you just use different keys?

I am having a problem with Time Machine, the error msg is "Time Machine.app can't be modified or deleted because it is required by MacOsX". It was working and now it is not.

Should have added that I am trying to retrieve back-up images.

How can I insert, modify and delete entries on my table control?

Hi,
I already have build a table control. Now I want to make manipulations on it. Therefore I have created 3 buttons, insert, modify and delete. But how can I get actions on table control.
This is my code for the internal table:
BEGIN OF its OCCURS 0,
mark TYPE C VALUE ' ',
artikel_nr TYPE ZARTIKEL-ARTIKEL_NR,
artikel_typ TYPE ZARTIKEL-TYPE,
bezeichnung TYPE ZARTIKEL-BEZEICHNUNG,
preis TYPE ZARTIKEL-PREIS,
mwst TYPE ZARTIKEL-MWST,
END OF its.
and this is the code which i wanted to delete a row in my table control:
WHEN 'DELETE'.
LOOP AT its WHERE mark EQ 'X'.
DELETE its WHERE mark = 'X'.
MOVE its TO ZARTIKEL.
ENDLOOP.
ENDCASE.
ENDMODULE:
and my PBO and PAI:
PROCESS BEFORE OUTPUT.
LOOP AT its INTO ZARTIKEL WITH CONTROL ARTIKEL.
ENDLOOP.
PROCESS AFTER INPUT.
MODULE EXIT.
LOOP AT its.
MODULE V1.
ENDLOOP.
MODULE user_command_1060.
But if I now open my table control and mark the line that I wanted to delete, nothing happens, not on my internal table and the data even not deleted on my table ZARTIKEL. Have you an idea what I did wrong??

Hi,
In the attributes of table control take the SELCOL as wa_zekpo-flag
And in the internal table and work area add a field as flag(1) TYPE c
Refer:
At screen logic:-
PROCESS BEFORE OUTPUT.
MODULE status_8002.
LOOP WITH CONTROL po_tab.
    MODULE pass_data.
ENDLOOP.
PROCESS AFTER INPUT.
MODULE user_command_8002.
LOOP WITH CONTROL po_tab.
    MODULE modify_data.
ENDLOOP.
MODULE function.
In PBO,
MODULE status_8002 OUTPUT.
SET PF-STATUS 'ZTG_SELTB'.
DATA : line_count TYPE i.
DESCRIBE TABLE it_ekpo
LINES line_count.
po_tab-lines = line_count + 5.
ENDMODULE.                 " STATUS_8002 OUTPUT
*&      Module PASS_DATA OUTPUT
MODULE pass_data OUTPUT.
READ TABLE it_ekpo into wa_ekpo INDEX po_tab-current_line.
ENDMODULE.                 " PASS_DATA OUTPUT
In PAI,
*&      Module USER_COMMAND_8002 INPUT
MODULE USER_COMMAND_8002 INPUT.
OK_CODE = SY-UCOMM.
CASE OK_CODE.
    WHEN 'BACK'.
      LEAVE TO SCREEN 8001.
    WHEN 'EXIT'.
      LEAVE PROGRAM.
ENDCASE.
ENDMODULE.                 " USER_COMMAND_8002 INPUT
*&      Module MODIFY_DATA INPUT
MODULE DISPLAY_DATA INPUT.
MODIFY IT_EKPO INDEX PO_TAB-CURRENT_LINE FROM WA_EKPO.
ENDMODULE.                 " MODIFY_DATA INPUT
*&      Module FUNCTION INPUT
MODULE FUNCTION INPUT.
OK_CODE = SY-UCOMM.
CASE OK_CODE.
    WHEN 'SELECT'. "<--select all records
      LOOP AT IT_EKPO INTO WA_EKPO.
        WA_EKPO-FLAG = 'X'.
        MODIFY IT_EKPO FROM WA_EKPO.
      ENDLOOP.
    WHEN 'DESEL'. "<--deselect all records
      LOOP AT IT_EKPO INTO WA_EKPO.
        WA_EKPO-FLAG = ' '.
        MODIFY IT_EKPO FROM WA_EKPO.

How can i modify or delete desktop files and folders in Mac OS 10.6.8 ?

i have Macbook pro running on Mac OS X, Snow Leopard ver. 10.6.8 . I am not able to delete rename and modify my desktop folder and files. even through the admin account and all previleges i cant move them to Thrash. as i try to delete them it asks for password and then no action takes place. i have even used repair permissions from disk utility, used the terminal window method but nothing happened. the "get info " shows read and write permision but still i cannot even rename them there.. can anyone please help me ?

Is the Desktop folder inside the Users -> Yourname folder with the same contents of your Desktop? If it isn't, then you've moved the Desktop folder to a place that can't be accessed by the account called Yourname.

HT201628 Okay I tried this but I can't put iTunes in the trash because it's "required by mac OS X".. What do I do?

iTunes doesn't recognize my iPhone... I just want to sync my phone...

Launch Activity Monitor in Utilities, select All Processes and see if you can see your application listed. Select it and click on the big red 'quit process' button at the top. Now try to delete the app.

Can't send cntrl-alt-delete to start PC remotely via Mac

I am using Symantec PC Anywhere software and even when I try the Mac equivalent of cntl-alt-delete the PC I am trying to connect to doesn't recognize the command. (Once I am in, the connection works fine). Any suggestions? Is there a better program out there to connect to a PC remotely via Mac?

I am using Symantec PC Anywhere software
Are you running Windows on the Mac (via Boot Camp, or Parallels Desktop or VMware Fusion) or is pcAnywhere CrossPlatform Remote (or something similar) used under Mac OS X?
the Mac equivalent of cntl-alt-delete
Just guessing here (I do not know whether the command in question will work at all when used via said remote control program). Would it be correct to assume that you have noticed the difference between the delete keys on a PC and a Mac (the delete key on a Mac is the same as backspace on a PC). You may want to have a look at this article (and perhaps this one).
Is there a better program out there to connect to a PC remotely via Mac?
When working under Mac OS X, could something like this (or maybe one of the programs here) possibly be of interest?

I can't run the installer file because a padlock appears in Mac OS X Yosemite.

When I download the file it appears on Finder with a padlock in the upper left corner. If I try to run it, it opens with another program that can't read it. Looking for some information on the internet I read something about the file permissions. But I don't know what to do.
Thanks for your time!!

Hi Maesgui,
In the screenshot, I see that the installer has the .mdlp extension. Do you by chance have MATLAB installed on your system?
Remove -2.mdlp from the file name and it should leave just the .dmg extension, which should launch. If it doesn't, right-click on the file and select 'Open With' and navigate to /System/Library/CoreServices/DiskImageMounter.app

Why can't I edit or delete Address Book "On My Mac" or sync with iCloud?

Why can't I edit or delete Address Book cards on my Macs, now that I've migrated to iCloud? I can edit/delete if I go to iCloud, but the changes don't sync with my Macs. What's happening, and what's a solution? Just wait for Apple to fix a bug?

On your mac, if your look at the left panel of the Address Book, you'll find general categories of "iCloud" and possibly "On my mac" - if you have contacts in the latter, then they are only local to your mac, they are not shared with iCloud. If you don't have an "iCloud" category, then your mac(s) is not set up of iCloud. Go to system preferences and look in iCloud. Is the mac signed into iCloud, are contacts turned on for syncing?

The operation can't be completed because backup items can't be modified.

In my Time Machine backup, I have also stored backups from my previous Mac. They do not appear in the "Star Wars" screen. When I try to delete files I receive the message: "The operation can’t be completed because backup items can’t be modified."
What does this mean, and is there a way to delete said files?
(My Time Machine backup is plugged in and running. The files are not even sent into the Trash, so my question doesn't relate to whether the files will delete from the trashcan, etc.)
Many thanks in advance for any and all help!

While in Time Machine, press the key combination shift-command-C. The front window will show all mounted volumes. All snapshots should now be accessible. Select the one you want and navigate to the files you want to delete. Right-click or control-click an item. From the popup menu, select Delete All Backups of... Confirm. Exit Time Machine.
