DIY Troubleshooting

Fix 1: Force Restart Touch Bar

Steps:

Fix 2: Kill TouchBarServer

Steps:

• Open Activity Monitor
• Search "TouchBarServer"
• Select it and click "X"
• Choose "Force Quit"
• Touch Bar will restart

Why It Works: The TouchBarServer process sometimes crashes.

Fix 3: Reset SMC

For T2 Macs (2018+):

• Shut down completely
• Press Ctrl + Option + Shift (left side) for 7 seconds
• While holding, add Power button for another 7 seconds
• Release all keys, wait 5 seconds
• Power on normally

For T1 Macs (2016-2017):

• Shut down
• Hold Shift + Control + Option (left side) + Power for 10 seconds
• Release all keys
• Power on

Fix 4: Reset NVRAM

Steps:

• Shut down
• Power on and immediately hold: Option + Command + P + R
• Hold for 20 seconds
• Release and let Mac boot

Why It Works: Clears stored settings that may affect Touch Bar.

Fix 5: Safe Mode Boot

Steps:

• Shut down
• Power on and hold Shift
• Release when login appears
• Test Touch Bar
• Restart normally

Why It Works: Safe Mode loads minimal software - helps identify software issues.

Fix 6: Update macOS

Steps:

• Apple menu > System Preferences
• Software Update
• Install any available updates

Why It Works: Apple has released multiple Touch Bar bug fixes.

Fix 7: Create New User Account

Steps:

• System Preferences > Users & Groups
• Create new user
• Log into new account
• Test Touch Bar

Why It Works: Determines if problem is user-specific.

When Software Won't Fix It

Hardware Issues Require Repair

If all software fixes fail, you likely have:

• Damaged Touch Bar strip
• Flex cable failure
• T1/T2 chip issue
• Logic board problem

Touch Bar Replacement

The Challenge: The Touch Bar is integrated with the display assembly. Replacing it often means:

• Full display assembly swap
• Or delicate Touch Bar-only replacement (skilled repair)

Costs:

Repair Type

Apple

RevivaTech

Display assembly	£400-600	£300-450
Touch Bar only	N/A	£150-250

Logic Board Issues

If the T1/T2 chip or display driver circuit has failed:

• May require logic board repair
• Component-level work possible
• Cost depends on specific failure

Living Without Touch Bar

If Repair Isn't Worth It

Some users choose to live with broken Touch Bar:

Workarounds:

• Use keyboard shortcuts instead
• External keyboard with function keys
• Touch Bar simulators (limited)

Limitations:

• No Esc key (big problem for developers)
• No brightness/volume slider
• Some apps require Touch Bar

Mapping Physical Keys

On 2018+ Models: System Preferences > Keyboard > Press Fn to: Show F1, F2, etc.

This makes Fn row usable but doesn't fix Touch Bar.

Preventing Touch Bar Problems

Good Practices

Do:

• Keep macOS updated
• Avoid moisture near keyboard
• Use proper shutdown (not just closing lid)
• Clean gently with microfibre cloth

Don't:

• Press excessively hard on Touch Bar
• Use liquid cleaners
• Ignore early warning signs
• Cover Touch Bar with tape/stickers

Early Warning Signs

Watch for:

• Occasional flickers
• Slight delays
• One unresponsive section
