Low and/or fluctuating signal strength collectively represent one of the most frustrating issues affecting iPhone owners. It can cause poor reception, dropped calls and other afflictions. The problem can be exacerbated by firmware updates, as recent reports have shown. We’ve received word of a new, potentially effective if unconventional workaround.

Time Machine problems a’plenty Time Machine continues to be the bane of Mac OS X 10.5.2 upgraders, causing a variety of issues that can hamper the function’s own operation or interfere with other system processes. The most common problems are:

• the error message “Unable to complete backup. An error occurred while copying files to the backup volume.”
• a situation where Time Machine is persistently “preparing” the backup but never actually starts backing up
• dismal backup speed

We’ve extensively covered this issue:

• MacBook, MacBook Pro update 1.1 doesn’t fix first-letter-missing syndrome
• MacBook, MacBook Pro update 1.1 effective for most users
• Sporadic missing letters while typing: Not just MacBook Pros; watch for trackpad interference
• MacBook Pros: First typed letter missing when typing in text fields; Apple acknowledges

The firmware update is available as an 875KB standalone download.

Per Apple’s instructions: “The update package will install an updater application into the Applications/Utilities folder and will launch it automatically. Please follow the instructions in the updater application to complete the update process.”

UPDATE: The fixes listed below can also help resolve an issue in which external displays do not come on at all while the notebook’s lid is closed and will not wake up when keys on an external keyboard or buttons on an external mouse are pressed.

One MacFixIt reader describes this issue:

“When I wake my MacBook Pro in closed-lid mode it shows the desktop picture on the external screen and then goes right back to sleep. If I then wake it again, the same thing will happen all over again. AC power is connected and the mouse/KB are working too so that’s not the cause of the problems. Somehow the MBP seems to constantly want to go back to sleep right after it wakes up.”

While Apple’s MacBook, MacBook Pro Keyboard Firmware Update 1.0 is proving effective for eliminating the “missing first letter” issue for users of MacBooks or MacBook Pros running Mac OS X 10.5.2, a large swath of users experiencing the problem: those who haven’t yet upgraded to Leopard or are using PowerBooks, still have no resolution. The new update requires Mac OS X 10.5.2 and is only applicable to MacBooks and MacBook Pros.

A number of users have reported that transfers of large files on local are dramatically slower under Mac OS X 10.5.2. MacFixIt reader John Albergo remembered a fix that we noted in our Mac OS X 10.4.9 special report that involves modifying the delayed_ack parameter of Mac OS X’s TCP/IP configuration by entering the following command in the Terminal (located in Applications/Utilities):

• sudo sysctl -w net.inet.tcp.delayed_ack=0

then pressing return.

This workaround solved his slow throughput immediately.

“I recalled an issue from around the time of the Macbook Pro introduction, for which the workaround was to force the tcp parameter “delayed_ack” to zero. Suspecting a return or variant of that bug, I tried the workaround on both of my machines and the slowdown has not returned.  I hesitate to declare a cure, but the throughput is rock solid so far, and at the speed I would normally expect.  This implies that delayed ACKs are not being delivered in a timely manner.

“The blogger at this site wrote a small install script at the time to put an item in Startup Items to do the same thing each time you boot up — making it easily removed when no longer needed.”

 Apple has posted a Knowledge Base document indicating that the MacBook Air (when equipped with either a hard drive or solid state drive) might show startup lower-than-expected volume capacity, resulting in “disk full” error messages.

The suggested solution is to format the startup drive (after creating a backup), making sure its in Mac OS Extended (Journaled) format and reinstall Mac OS X.

Of course, you’ll need another computer’s optical drive (to boot via Remote Disc) or the external MacBook Air SuperDrive in order to perform this operation.

UPDATE: A separate Knowledge Base article notes that the MacBook Air SSD should only have a total of 55.9GB of capacity.
