MacWorld reports that Apple on Monday released Mac OS X 10.5.4 fixing several issues with iCal, AirPort, Safari, and Spaces & Exposé. The update is available from Mac OS X Software Update or directly from Apple’s Web site.

The BBC points out that the Tuguska Event occurred 100 years ago today. At 7:17am on June 30,1908, an immense explosion tore through the forest of central Siberia. Some 80 million trees were flattened over an area of 2,000 square km (800 square miles) near the Tunguska River. The blast was 1,000 times more powerful than the atomic bombs dropped on Hiroshima and Nagasaki and generated a shock wave that knocked people to the ground 60km from the epicentre. The cause was an asteroid or comet just a few tens of metres across which detonated 5-10km above the ground, and eyewitnesses recalled a brilliant fireball resembling a "flying star" ploughing across the cloudless June sky at an oblique angle.

I worked with Frank Mott many years ago when we were both in IT sales. He is a good guy, genuine, hard worker. He takes care of his customers, and he loves Macs. Frank has bought the store formerly known as Delaware Computer Exchange. Now with new management and a new name, Mac Exchange is having a coming out party!

Jefferson Consulting's office will be closed this Wed 6/11 through Friday 6/13.

Dear .Mac member:
Today Apple announced a new Internet service called MobileMe - taking the best of .Mac and adding a host of new features. As a current .Mac member, your account will be automatically upgraded to MobileMe in July. For a closer look, watch the MobileMe Guided Tour and read below for an overview of your new service.
Mac integration you know and love. With MobileMe, you'll continue to enjoy features that take advantage of seamless integration with Mac OS X and iLife - Back to My Mac; access to your iDisk in the Finder; Mac-to-Mac syncing of Dock items, preferences, and more; iWeb site publishing; and photo and movie sharing directly from iPhoto '08 and iMovie '08.
New web applications for when you're away from your Mac. MobileMe features a suite of web applications at www.me.com that have the familiar look and feel of the applications on your Mac. Because these web applications stay in sync with your Mac and other devices, you'll have the same information wherever you go. Here's what you'll find at me.com:
Mail, the anchor of the new suite, is even better with a refined interface.
Contacts has a new three-pane interface, contact groups, maps integration, search, and photo support.
Calendar is a brand-new web application that feels just like iCal, featuring multiple calendars, click-and-drag event creation, and more.
Gallery lets you manage your collection of shared photos and movies from anywhere. You can now upload photos, rearrange their order, and set sharing preferences, all from a browser.
iDisk now has the familiar look of the Mac OS X Finder. It features drag-and-drop filing and an easy new way to share large documents, by sending an email with a link for downloading the file.
Account lets you manage settings such as storage allocation.
To use the new web applications, make sure you have one of these browsers: Safari 3, Internet Explorer 7, or Firefox 2 or later.
Push email. Push contacts. Push calendar. In addition to Mac-to-Mac syncing, MobileMe now keeps your iPhone, your iPod touch, and even a PC in sync. MobileMe pushes new contacts, calendar items, and bookmarks to your Mac or PC, and over the air to your iPhone or iPod touch. For example, if you add a calendar event on the web, the change will automatically be pushed to your Mac and iPhone. New email will be pushed to your iPhone in seconds, eliminating the need to check for messages manually.
As a MobileMe subscriber, you can continue to use your mac.com address for email. You will also be issued a me.com address with the same user name that you can use if you prefer. The choice is yours.
Double the online storage. To give you plenty of space for your email, photos, and other files, MobileMe doubles your storage from 10GB to 20GB for an individual subscription.
We'll be sure to update you when the new service goes live. In the meantime, if you have any questions about the upcoming transition from .Mac to MobileMe, please visit the MobileMe FAQ.
Sincerely,
The MobileMe Team

Introducing MobileMe. A new service for your iPhone, iPod touch, Mac, and PC. "The simple way to keep everything up to date." As one blogger put it, this is "Exchange for the rest of us."
