In advance of Monday's keynote address by Steve Jobs at WWDC The PowerPage has received a alleged copy of the features (and some screenies) from Apple's next generation operating system - Mac OS 10.5 ("Leopard"). The details are unconfirmed and are being posted for informational purposes only.

Mac OS 10.5 will see updates to most of the included applications, among the major updates are:

• Spotlight 2.0
• Dashboard 2.0
• Safari 3.0
• iChat 4.0
• Automator 2.0
• QuickTime 7.2
• Mail 3.0
• iCal 3.0
• Address Book 5.0

The updates are as follows:

Spotlight 2.0:

- Spotlight's icon changes to suit the new apple menu logo
- Instead of words down the side i.e. applications, system preferences... there are icons of each at a user defined size (80 x 80 default). So for applications there is the global application icon, and next to the hits and so on.
- The icons of the hits will be larger and for documents, events, mail, images, PDF's movies, fonts and presentations. there will be little live icons. For documents, the icon of the app (word or pages), events; the iCal icon with the date of the event and the time on it.
- Image previews will be larger but there will also be a little text of the type of image i.e. jpg in a contrasting color in the bottom right of the preview. PDF's will just be larger, movies will have a little preview at about 8x the speed (or less fast depending on the length) that will be cached in the finder.
- Fonts will be in the font type.
- Presentations will preview just like movies.
- If any of the items are in an open window, on the desktop, or in an app (bookmarks in safari, or a library item in itunes etc.) and the app is open, the rest of the app will fade and the specific items will light up, and if more than one, in the examples given, the app will just give a standard search and safari will open the bookmark browser.

- The same goes if it is on the desktop, the spotlight will shine on the icon(s).

- There will be the standard presumed better metadata searching. So if the majority of results are images, the show all pane at the right will also allow to organize by camera, date taken, file type and app used. The most used app and file type at the top of its respective lists.
- Spotlight will also search widgets
- The slideshow feature will be enhanced for most filetypes. Documents can be previewed in a similar way to images are now and so on and so forth.
- Also spotlight will actually be almost instantanteous or as instant as they can hope.
- A new spotlight widget.

Dashboard 2.0:

- Dashboard will get a system preferences icon.
- Dashboard will appear in the application switcher.
- Widgets can now be placed on the desktop. If one drags an icon to the board and waits two seconds in one place the board will fade out and you can place it on the desktop. The icon will appear in the dock and will be treated as an app.
- You can also keep widgets in the dock, either by dragging them there from dashboard or keeping them there when they appear on the desktop.
- In the dock will be the x icon for closing the widget on top of the widget icon, not on the widget itself.
- There will be also a selection of different animations.
- You can isolate dashboard in a similar way to front row, you can push the desktop as an expose item to the side and isolate dashboard that way.
- You can isolate dashboard also via a cube effect. Also you can open dashboard in a similar way to f11, the widgets will hide at the side and come forward for use, in this one, the dashboard will not be isolated. Hot corners and f numbers can be configured to use one of them each. so you can have a different function key for each affect.
- In the isolated dashboard, the background will be black, but it will act as a pool of water, in a similar way as to now, so when you drag an widget around, you can create ripples.
- Also you can choose from water, air, space and metal as your chosen set of widget animations. Air and metal animations are not elaborated on, but space acts a bit like a black hole when you remove a widget and the widgets 'zoom' on.
- New widgets.

Safari 3.0:

- Phishing filter
- Tighter RSS
- Integrated FTP
- Integrated mailto function, a mail plugin that lets you send emails without opening Mail.
- Isolation box. When this is activated, Safari grows a little black shield around it and everything to do with Safari takes place instead in an encrypted disk image of a special filesystem that nulls unix permissions, anything that is written goes there and can't execute out of the image. The image is deleted after the session.
- Tabs can now operate on more than one line, and be saved.
- A safari Exposé is available, allowing Web pages in tabs to be treated as separate windows for the time of the Exposé .
- Web pages can be "Widgetized." You can make a new separate widget of a Web page, there is also a mini Safari widget that just has back and forward buttons and a small address bar.
