Install LocalDevVPN, connect, open SideStore, sign in, and refresh

Success! SideStore is now fully installed and ready to sideload apps wirelessly.

Beyond SideStore: Other iLoader Features

iLoader isn’t just for installing SideStore. It’s a full-featured sideloading toolbox.

📱 Sideloading Any IPA File

Want to install a tweaked app directly, without going through SideStore? iLoader can do that [citation:iLoader Docs].

Connect your device and open iLoader
Look for “Install IPA” or “Sideload IPA” option
Browse and select your .ipa file
Confirm installation and wait for completion
The app appears on your home screen (trust the developer if prompted)

Use cases:

Installing apps before SideStore is set up
Testing IPA files quickly
Installing apps that might conflict with SideStore’s management

🔐 Certificate Management

Development certificates are the keys to sideloading. iLoader gives you full control [citation:iLoader Features].

View Certificates: See all active certificates, their expiration dates, and types
Revoke Certificates: Remove old or unused certificates (be careful—this breaks apps signed with them!)
Create New Certificates: Generate fresh certificates when needed

Why manage certificates?

Apple limits how many certificates you can have
Expired certificates cause installation failures
Revoking unused ones frees up space for new ones

🔑 Pairing File Management

Pairing files are essential for apps like SideStore, StikDebug, and Protokolle to communicate with your device. iLoader handles them effortlessly [citation:iLoader Features].

Automatic placement during SideStore installation
Import/export for backup or transfer
Replace when files expire (common after iOS updates)
Manage files for multiple apps in one place

👤 Multiple Apple ID Support

If you manage devices for family members or use different accounts for testing, iLoader’s multi-account feature is a lifesaver [citation:iLoader Features].

Save multiple Apple ID credentials securely (local storage only)
Switch between accounts with a single click
Per-device account assignment
No need to re-enter credentials repeatedly

Platform-Specific Guides

Windows Deep Dive [citation:iLoader Download]

Key considerations:

iTunes must be installed for usbmuxd drivers—this is non-negotiable
Always run iLoader as administrator for best results
If Windows Defender blocks iLoader, add an exclusion or temporarily disable real-time protection

Portable vs. MSI:

MSI installer: Better integration, adds Start Menu shortcut, handles updates
Portable EXE: No installation needed, great for USB drives or temporary use

macOS Deep Dive [citation:iLoader Download]

Key considerations:

No additional software needed—usbmuxd is built into macOS
Universal binary works on both Intel and Apple Silicon
Gatekeeper may block first launch—use right-click → Open to bypass

Security note: If you see “iLoader cannot be opened because the developer cannot be verified,” this is normal for open-source apps not notarized by Apple. The app is safe (you can audit the code on GitHub).

Linux Deep Dive [citation:iLoader Download]

Key considerations:

usbmuxd installation varies by distribution—use the commands provided above
After installing usbmuxd, ensure the service is running: sudo systemctl start usbmuxd
Add your user to the plugdev group for device access: sudo usermod -a -G plugdev $USER (log out and back in)

AppImage advantages:

Works on any distribution without installation
Self-contained with all dependencies
Just make it executable and run

Troubleshooting Common Issues

Based on the official documentation, here are solutions to the most frequent problems [citation:iLoader Docs] [citation:iLoader FAQ].

“Device Not Detected”

Platform	Solutions
All platforms	Try different USB cable/port, restart both devices, unlock device and keep screen on
