| Click here to return to the '10.4: Cascade all windows via a hidden menu option' hint |
So, try the File menu. :)
'Close all windows' and 'Close other tabs' magically appear. yay! too cool. Now to start all 746 apps i have on my poor little iBook and see what happens with them!
It works in 10.3.9 as well. Seems to put the most recently-used (clicked) window at the front, with title bars in 'cascade' fashion, but not resizing the windows, just moving the title bar to the cascade position. How long has that been there I wonder. If it had been just 10.4 I'd have thought they were targeting the 'switchers' from Windows, but it's not so obvious.
But the option to kill all other tabs is mega!!!
Other day guy walked into my office.
'What's the exchange rate for the NTD?'
Aha! Dashboard.
Yes. If nobody did, there wouldn't be about a zillion widgets available for it.
I use about 3 or 4 regularly.
While the 'arrange in front' menu option doesn't appear in Omniweb (5.1b), there is an interesting 'option' that appears in the File.. Monument stack 1.0 (mac) mac os. menu - 'Save as PDF'.
Very useful!
(I went and tried holding option down on a load of apps too.. ;-))
I don't know. I've known Windows users who say this has been one of the weaknesses of MacOS. I know there are situations where I wish I could cascade a bunch of Windows. And my experience shows that the current active window is the one that ends up in front. But more testing is required.

Also, in the 'Window' menu item, 'Minimize' changes to 'Minimize All' which could be useful.
This doesn't work in Transmit 3.2 on my machine. The rest – fine. Just not in Transmit. Nor do any optional menu commands come to think of it.
It's not just the Window menu that has the option key feature.
Try the other menus in Finder and Safari.
You can empty the trash without the dialog.
This also seems to affect the 'apple'-menu where 'Reboot..' changes to 'Reboot' without the dots, the same goes with 'Shut down..' and 'Log out [username]..'. Also the 'Log out'-option changes it keyboard shortcut when holding down the alt-key.
for those of you not familiar with the ellipsis, in the menu, they mean that there will be a dialog box if you choose that item.
Therefore the choosing these items with the option key down will activate the command chosen with no user feed back.
The 'Arrange Windows in Front' command has been around in most previous versions of Mac OS X. It is not just limited to Tiger. Likewise the other options people are talking about: Reboot, Logout, etc., have also behaved differently with the option key held down. The general behavior of the option-key revealing hidden items in menus has been around since Mac OS 7 (for those programs that used the popular Mercutio MDEF) and the modification of behaviors with the option key held down has been an integral part of the Mac for as long as I can remember.

Sometime last year when I discovered the 'Close All Windows/Other Tabs' option in Safari, I submitted it as a hint and was subsequently rejected with the reply 'it is 'just' a documented menu-item hint, which we don't generally run', from Rob.
I guess the rules have changed. ;)
You are right; option key has had the affect of providing an optional action ever since it appeared on the keyboard, but a) I'd never seen window cascade before - may not be new to tiger, but still faily new - and b) lots of people here have now been scurrying around their Mac UIs looking for other uses of it, so that can't be a bad thing.
:-)
Way to go! This hint is falling very short of its potential. :)
You can press and release the option key while a menu is open to see what changes. It works on right-click (context) menus as well, so you can right-click on a file in Finder, and use the option key to select 'Always Open With..' right from the menu.
In the Finder option-context-menu, you can also open the Inspector Window (which I'd never heard of before). This stays open, and always shows the properties of whatever file is currently selected.
Thanks for bringing up the CM aspect of this opt key behavior! I discovered that when ctrl-clicking a Safari link, and hitting opt, 'Download Linked File' becomes 'Download Linked File as..' allowing me to choose where to save each file. VERY USEFUL!! Now if only I could set this as the Safari's default behavior!
You can also hold down option while clicking the green resize button and the same cascading will occur :)
This is kind'a VERY OLD NEWS!
I can remember back to QuickTime Player 3 (or Movie Player 3 as I think it was called then), here you had tons of ALTERNATE OPTIONS becomming available in the menus when you held down the ALT/OPTION-key.
So the recent things that are 'brought to live' in Tiger actually has it's methods from almost a decade ago!!!
In addition to omniweb and transmit mentioned above, it doesn't work in firefox, Microsoft Word (so I'm assuming all of Office), subethaedit, pixadex, superduper, notetaker or iterm. It does work for the window menu of newsfire, iBiz and TextMate but not the file menu. The Adobe and Macromedia suites seem to use a different menu layout for their window menus so there isn't a bring all to front to change. *shrug*
It actually orders the windows alphabetically by title
No, this is very helpful! I use two monitors at work. When I come home, some of my windows are off-screen, and I can't get to them. The Gather Windows option in display preferences is disabled in single monitor mode for some annoying reason, so this option just saved me. In windows, you just hit alt-space and 'm' to move your windows manually, but you can't do anything like that on Mac. Thanks for this posting. I wouldn't have found it otherwise.
Apple Partition Map (APM) is a partition scheme used to define the low-level organization of data on disks formatted for use with 68k and PowerPCMacintosh computers. It was introduced with the Macintosh II.[1]
Disks using the Apple Partition Map are divided into logical blocks, with 512 bytes usually belonging to each block. The first block, Block 0, contains an Apple-specific data structure called 'Driver Descriptor Map' for the Macintosh Toolbox ROM to load driver updates and patches before loading from a MFS or HFS partition.[2] Because APM allows 32 bits worth of logical blocks, the historical size of an APM formatted disk using small blocks[3] is limited to 2 TiB.[4]
Menu new game+ mac os. The Apple Partition Map maps out all space used (including the map) and unused (free space) on disk, unlike the minimal x86 master boot record that only accounts for used non-map partitions. This means that every block on the disk (with the exception of the first block, Block 0) belongs to a partition.
Some hybrid disks contain both an ISO 9660 primary volume descriptor and an Apple Partition Map, thus allowing the disc to work on different types of computers, including Apple systems.
Intel-based Macs[edit]
For accessing volumes, both APM and GUID partitions can be used in a standard manner with Mac OS X Tiger (10.4) and higher. For starting an operating system, PowerPC-based systems can only boot from APM disks[5] whereas Intel-based systems generally boot from GUID disks.[1][6][7] Nevertheless, Intel-based Macs are able to boot from APM, GPT (GUID Partition Table) and MBR (Master Boot Record, using the BIOS-Emulation called EFI-CSM i.e. the Compatibility Support Module provided by EFI).
Intel-based models that came with Mac OS X Tiger (10.4) or Leopard (10.5) preinstalled had to be able to boot from both APM and GUID disks due to the installation media for these universal versions of Mac OS X, which are APM partitioned in order to remain compatible with PowerPC-based systems.[8] However, the installation of OS X on an Intel-based Mac demands a GUID partitioned disk or will refuse to continue, the same way installation on a PowerPC-based system will demand an APM partitioned destination volume. Cloning an already installed OS X to an APM partition on Intel systems will remain bootable even on 2011 Intel-based Macs. Despite this apparent APM support, Apple never officially supported booting from an internal APM disk on an Intel-based system. The one exception for a universal version of Mac OS X (Tiger or Leopard) is an official Apple document describing how to set up a dual bootable external APM disk for use with PowerPC and Intel.[9]
Layout[edit]
Each entry of the partition table is the size of one data block, which is normally 512 bytes.[1][10] Each partition entry on the table is the size of one block or sector of data. Because the partition table itself is also a partition, the size of this first partition limits the number of entries to the partition table itself.
Concealed Intent Mac Os X
The normal case is that 64 sectors (64 × 512 = 32 KB) are used by the Apple Partition Map: one block for the Driver Descriptor Map as Block 0, one block for the partition table itself and 62 blocks for a maximum of 62 data partitions.[11]
Each partition entry includes the starting sector and the size, but also a name, a type, a position of the data area and possible boot code. It also includes the total number of partitions in that partition table.[12] This ensures that, after reading the first partition table entry, the firmware is aware of how many blocks more to read from the media in order to have processed every partition table entry. All entries are in big-endian byte-order.[citation needed]

| Apple_Rhapsody_UFS | Unix File System | Mac OS X Server | This partition contains a Unix File System (UFS) used by the Apple Rhapsody operating system (a development name marking the transition from OPENSTEP to Mac OS X) and is also used by Mac OS X Server 1.0 through 1.2 v3. |
| Apple_Scratch | empty | This identifier marks an empty partition. | |
| Apple_Second | Second stage bootloader | ||
| Apple_UFS | Unix File System | Mac OS X | This partition contains a Unix File System (UFS) and is used by Mac OS X, Mac OS X Server (Version 10.0 and newer) and various Unix-like operating systems. |
| Apple_UNIX_SVR2 | A/UX, Unix | Originally introduced for A/UX (Apple Unix operating system based on System V Release 2, hence SVR2) on the 68k, it was later reused for MkLinux which used the Extended file system. It is the standard partition identifier for many Unix-like operating systems, including Linux and NetBSD. It may contain any file system suitable for the installed operating system. If bootable, a file system that can be read by the Open Firmware bootloader from Apple_Bootstrap (e.g. yaboot) must be used. | |
| Apple_Void | A dummy partition map entry to ensure correct partition alignment on bootable media. | ||
| Be_BFS | Be File System | This partition contains a Be File System (BFS) and is normally used by BeOS. | |
| MFS | TiVo Media File System | MFS application region, MFS media region | Used to hold the proprietary Media File System on TiVo hard drives formatted using Apple Partition Map. |
