What we do for Mac clients

Full-lifecycle Mac management for your business — not guesswork.

Apple Silicon vs Intel — what still matters in late 2026

Every Mac Apple sells today is Apple Silicon (M-series chips). Buying new means there's no decision to make. For the Intel Macs still in your office:

• Intel Macs still work fine. But macOS Tahoe (version 26) is the last major macOS release that supports Intel hardware. From here on, Intel machines get security updates only — Apple has committed to three years of security updates following Tahoe's September 2025 launch, coverage through roughly fall 2028. No new macOS versions, no new features.
• Old Intel-only apps on Apple Silicon? Rosetta 2 translates most of them without anyone noticing. If you have a critical line-of-business app, we test it before we migrate anyone.
• Windows on a Mac: Intel Macs could run Windows natively with Boot Camp. Apple Silicon Macs can't — Boot Camp is gone. Windows 11 runs in a virtual machine (Parallels Desktop or VMware Fusion), and we set that up. See below.

Managing the Macs: MDM

Once you've got more than a couple of Macs, managing them by hand doesn't work. Mobile device management (MDM) lets us push settings, apps, and security policies to every Mac from one console, over the internet — Dover office or home office, doesn't matter. Here's how the main options compare for a small business:

Prices are approximate and change. Check current pricing before quoting a client. Figures checked October 2026.

Our recommendation for SMB: Mosyle. It covers what a small business needs: zero-touch enrollment, configuration profiles, app deployment, patch enforcement. The price doesn't punish you for growing. Jamf Now is fine if you're tiny and want the simplest possible start. And if your company already runs on Microsoft 365, Microsoft Intune can manage Macs too — we pick the tool that fits your business, not the one with the best logo.

Apple Business Manager (ABM)

What it is: Apple's free web portal (business.apple.com) that ties your company's Apple devices, app licenses, and employee Apple accounts together. It's not management software by itself — it's the foundation your MDM plugs into.

Why you need it

• Zero-touch enrollment. Macs and iPhones bought from Apple or an authorized reseller register themselves with your MDM the first time they're turned on. No technician in the loop, no setup checklist taped to the box. This is the big one.
• Supervised devices. ABM enrollment puts devices in supervised mode, unlocking the strongest management controls: mandatory profiles, remote wipe, app lockdown.
• Managed Apple Accounts. Your company, not the employee, owns the Apple accounts used for work. When someone leaves, the account and its data stay with you.
• Volume app licensing. Buy app licenses once, assign them to devices, reclaim them when someone leaves.

How we onboard you

1. We enroll your company at business.apple.com. Apple verifies the business — you'll pick two verification methods from Apple's current options: a D-U-N-S number or EIN, a business license upload, domain validation via a DNS TXT record, or official documents such as a utility bill, energy bill, or property lease. A D-U-N-S number alone is no longer strictly required. Approval usually takes a few business days.
2. We connect your MDM to ABM and link your Apple reseller, so every new device you buy flows in automatically.
3. We create your Managed Apple Accounts and set the enrollment profile.
4. From then on, a new Mac arrives, the user opens the box, and it configures itself. Done.

Devices you already own can be added manually with Apple Configurator, but there's a 30-day window where the user can remove the management. Buy through your reseller once ABM is set up and that problem goes away.

Mac + Microsoft 365: yes, they work together

Plenty of Delaware businesses run Microsoft 365 and hand their people Macs. That works fine when it's set up properly. That's what we do.

• Outlook, Teams, OneDrive, Office apps all run natively on macOS. They're first-class apps, not watered-down Mac versions.
• One sign-in. With Microsoft's Platform SSO for macOS (generally available), your people sign into the Mac with their Microsoft Entra ID credentials and stay signed in across Office apps and browsers — including passwordless options backed by the Mac's Secure Enclave.
• Managed like everything else. We enroll Macs in Microsoft Intune (or your Apple MDM of choice), so Conditional Access policies apply: compliant device, required sign-in strength, company data stays in company apps.
• OneDrive backs up the Mac's Desktop and Documents folders and keeps files available on demand, same as on Windows.

Mac security baseline: every machine, no exceptions

The checklist we apply to every Mac we manage. If a box isn't checked, we know about it.

• FileVault on. Full-disk encryption, recovery key escrowed to your MDM, not written on a sticky note.
• Automatic updates on. macOS and apps update on schedule. We verify it.
• Gatekeeper enforced. Only signed, notarized apps run. No random internet downloads becoming your problem.
• Built-in malware protection active. XProtect and Malware Removal Tool are Apple's background defenders — they only work well if the Mac is actually updating.
• Firewall on. macOS application firewall enabled, stealth mode where it makes sense.
• Sign-in policy. Minimum password/passcode length, lock screen after inactivity, Touch ID where the hardware supports it.
• Standard users, not admins. Day-to-day accounts run without admin rights. Admin credentials stay with IT.
• Find My enabled. A lost or stolen Mac gets located, locked, or wiped remotely.
• Endpoint protection. For businesses with compliance needs or real risk, we layer a managed EDR agent on top of Apple's built-ins.

Mac backup

The rule we live by: if we haven't restored from it, it isn't a backup. We verify restores on a schedule and document the results. Ask us to prove it, and we will.

Windows 11 on your Mac — Parallels vs VMware Fusion

Boot Camp is gone on Apple Silicon Macs, but you can still run Windows 11 in a virtual machine. Here's the comparison.

What to know before you commit

• It's Windows 11 for ARM. Most regular Windows apps run fine through built-in emulation, but anything that needs special hardware drivers must have an ARM64 version. We check your must-have apps first.
• You still need a legitimate Windows 11 license.
• Give the VM enough resources — 8 GB RAM minimum to Windows on a 16 GB Mac, more if you're doing real work in it.

We run what we sell: our own test lab is a MacBook Pro running macOS, Windows 11 (ARM), and Linux VMs side by side. We test client setups on that rig before we deploy them to you.

Common Mac issues — the runbook

What we see in the field and how we fix it. Symptom, then fix.

1. WiFi drops or won't connect. Forget the network and rejoin. If it persists, renew the DHCP lease (System Settings → WiFi → Details → TCP/IP), then check for VPN or security software fighting the connection. Still dead? Test another network to isolate the Mac from the router.
2. Printer won't print. Most modern printers are AirPrint. Delete the printer and re-add it, and macOS pulls the right driver itself. USB printer acting up: reset the printing system (right-click in Printers & Scanners, “Reset printing system”), then re-add.
3. iCloud stuck syncing. Check storage — when iCloud is full, sync stops silently. Sign out and back in only as a last resort. First try toggling the specific service (Drive, Photos) off and on. Never “fix” sync by deleting local files.
4. App asks for permissions over and over. Go to Privacy & Security settings, remove the app from the list, re-add it, and restart the app. If it keeps looping, the app bundle is damaged — reinstall it.
5. Mac is slow. Check login items (General → Login Items) and remove what doesn't need to be there. Check free space — under ~10–15% free and macOS chokes. Then open Activity Monitor, sort by CPU, and find the hog.
6. Spinning beach ball in one app. Force quit the app (Option-Command-Esc). If it happens every launch, hold Shift while opening it or reinstall.
7. External display not detected / wrong resolution. Reseat the cable — half of these are the cable. Then go to Displays settings and hold Option to reveal the Detect Displays button. Cheap USB-C dongles cause most of the rest.
8. Bluetooth mouse/keyboard lagging or dropping. Move USB 3 drives and dongles away from the Mac, since they interfere with Bluetooth. Unpair and re-pair the device. Check the battery.
9. “App can't be opened” / Gatekeeper block. If you trust the source, right-click → Open. If it still refuses, the quarantine flag is stuck, and we clear it from Terminal. Never disable Gatekeeper system-wide to fix one app.
10. Time Machine backup failing. Verify the drive mounts in Finder. Check available space on the backup volume. “Backup delayed” usually means the Mac hasn't been on the network or near the drive. Delete old snapshots only if the drive is genuinely full.
11. Forgot Mac password / locked out. If the FileVault recovery key is escrowed (ours always is), we reset the password with it. Without the key and without another admin account, the data is gone — that's why the key gets escrowed on day one.
12. Keychain keeps asking for password. After a password reset, the login keychain is out of sync. Fix: Keychain Access → Settings → “Reset Default Keychains.” The old keychain is archived, not deleted, so passwords can be recovered from it.
13. Mail/Outlook not syncing. Remove and re-add the account. For Microsoft 365 accounts, sign out of the Entra SSO session and re-authenticate. Stale tokens are the #1 cause.
14. Battery draining fast. Check battery health (System Settings → Battery). Look for the culprit in Activity Monitor → Energy tab. Background photo analysis and Spotlight indexing after an update are the usual temporary causes.
15. Spotlight not finding files. Rebuild the index: open the Privacy tab in Spotlight settings, add the drive, remove it, and macOS reindexes. It takes a while on big drives — let it finish.
