iMac Repair Australia — M-Series & Intel
Last Updated:
Apple’s iMac is the all-in-one desktop — currently the 24″ with Apple Silicon (M1, M3, M4), with the legacy 21.5″ and 27″ Intel models (including the 5K Retina 27″) still very much in use across Aussie creative studios, education and home offices. We repair every iMac generation back to the Unibody era. Big advantage of iMac over MacBook: most repairs are doable onsite — your iMac doesn’t move easily, so we come to you.

Common Issues & How We Fix Them
Cracked Retina 5K / 4K display
Bonded glass + LCD. Replacement requires careful re-bond. 21.5″ 4K: $850-$1,100 fitted. 27″ 5K: $1,400-$1,800 fitted. 24″ M-series: $950-$1,300 fitted.
Fusion Drive failure
The 27″ 5K Intel iMac used Apple’s “Fusion Drive” — small SSD + spinning HDD presented as one volume. SSD wears, HDD ages, the pairing fails. We split the Fusion Drive into discrete SSD + (optional) HDD, OR upgrade to pure NVMe. $380-$580 fitted plus drive cost.
Power supply failure
iMac PSU board is a known failure mode at 5-7 years. Replacement PSU board: $280-$420 fitted onsite or workshop.
Fan noise / dust
iMac fans run constant — dust accumulates over years. Deep clean: $180-$240 onsite.
HDD upgrade to SSD (any Intel iMac)
The single biggest performance upgrade for any pre-2019 iMac. SSD swap with full clone: $280-$420 + SSD cost. 5x faster boot, dramatically smoother daily use.
GPU failure (iMac 27″ 5K + iMac Pro)
Discrete AMD Radeon Pro GPUs in 27″ 5K develop BGA fatigue. Reflow / reball: $480-$880.
Won’t power on
6-step diagnostic. Often the PSU. Free diagnostic onsite.
Stuck at Apple logo / boot loop
Fusion Drive corruption common cause on 5K. We boot from external macOS installer, repair, restore. $180-$280 with data preserved.
Yellow tint / screen burn-in (older iMac)
Backlight aging on 21.5″/27″ 2012-2016 iMac. Backlight replacement special-order. Quote case-by-case.
